Frequently Asked Questions - TS-3000-248B Mean Well

How do I set the output voltage and frequency on the TS-3000-248B?

With the inverter switched off and batteries connected, press and hold the setting button (using an insulated stick) for 5 seconds until a beep sounds. Then follow the LED indications in the manual to select the desired voltage/frequency combination. Hold the button for 3-5 seconds to confirm and move to the next step.

What is the difference between the TN-3000 and TS-3000 series?

The TN-3000 series includes both an AC charger and a solar charger, allowing battery charging from utility or solar panels. The TS-3000 series is an inverter-only unit without built-in chargers. The TS-3000-248B requires an external battery charger for recharging.

What type and capacity of battery is recommended for the TS-3000-248B?

Lead-acid batteries are recommended. For the 48V model (TS-3000-248B), a minimum capacity of 100Ah is suggested. Ensure all batteries in a bank are the same brand and model.

How should I install the inverter for proper cooling?

Mount the inverter horizontally on a flat surface. Ensure at least 15cm of clearance on both the front and rear ventilation slits. Do not stack objects on top of the inverter. Avoid installing in high moisture or high ambient temperature locations.

What protections does the TS-3000-248B have?

The inverter includes input reverse polarity protection (via internal fuse), over voltage protection, under voltage protection (battery low alarm and shutdown), output overload protection (3000-3450W for 3 minutes, >3450W instant), output short circuit protection, and over temperature protection.

Can I use the TS-3000-248B with solar panels?

The TS-3000-248B is an inverter-only unit and does not have a built-in solar charger. To use solar panels, you need an external charge controller and a separate battery charger. The unit can then invert the stored DC power from batteries to AC.

How do I connect the optional remote control module (IRC series)?

Connect the IRC module to the communication port on the front panel using the provided cable (10FT standard). This allows remote ON/OFF control, enabling/disabling saving mode, and monitoring inverter status. Extended cables (25FT/50FT) are optional.

What should I do if the inverter shuts down?

Check the LED display for failure indications. Possible causes: input voltage out of range, over temperature (ensure ventilation and reduce load), overload (reduce load or check start-up current), short circuit (check wiring). If the AC outlet has no voltage, check the no-fuse breaker (resettable) on the front panel.

Is the TS-3000-248B suitable for inductive or motor loads?

Yes, the inverter can handle inductive loads such as motors, but note that starting current can be 6-10 times the rated current. Ensure the peak surge current does not exceed 6000W. For capacitive loads like switching power supplies, start with no load and increase gradually.

What is the warranty period for the Mean Well TS-3000-248B?

4. Explanation of Operating Logic

TN-3000 is CPU digital controlled true sine wave DC/AC inverter. It is designed to achieve the target of energy conservation and possesses both UPS and energy saving modes. These 2 modes are user adjustable. The unit will be factory set in the UPS mode. Depending on weather and utility conditions, users can manually adjust (refer to section 5.3) or use the monitoring software to switch to the energy saving mode.

The main difference between the UPS and Energy saving mode is the amount of energy conserved. Under the UPS mode, the unit will remain in the bypass mode as long as utility is available, thus less energy is conserved (refer to figure 4.1 for details of UPS mode control logic). Under the Energy saving mode, the priority of input source chosen is solar panel AC utility battery. If available, the CPU will automatically select external solar panel as its first priority in order to conserve energy. In case of insufficient solar power and utility failure, battery power will be drawn as the last the last resort. When the capacity of batteries drops to around 10 20% , the CPU will remind the end user by continuously sending out warning siren until the system shuts down.

4.1 Explanation of UPS Mode Control Logic

Figure 4.1 Diagram of UPS mode control logic

t1: To ensure the battery is at full capacity, when the TN-3000 is turned ON, the CPU will execute the "bypass mode" automatically connecting the AC main to the load. In the meantime, it will activate both the AC charger and solar charger to simultaneously charge the batteries.
t2: When the batteries are full (battery voltage around 28.5V), both the AC and solar charger will be turned OFF by the CPU to prevent overcharging and reducing battery lifetime.
t3: At this time period, TN-3000 is still in the bypass mode. The battery voltage level will decrease gradually due to standby power dissipation. When the batteries are consumed to around 90% of their capacity (battery voltage around 26.5V) the CPU will restart the charger. The CPU will use solar charging current of 3A as a guideline. When the provided charging current is >3A (solar charge LED indicator turns ON), the solar charger will be used to charge the battery. When the provided solar charging current is under 3A, the AC charger will be turned ON (e.g. night

time or cloudy day) taking over battery charging duty and at this time the solar charger indicator will turn OFF.

t4: With the charger activated, voltage of the battery bank will increase gradually until 28.5V is reached then the CPU will shut off the charger to prevent over charging. At this time, output load is still supplied by utility.

t5 : If utility were to fail at this moment, the CPU will automatically switch (<10ms) to the inverter mode insuring uninterrupted power.

t6 : Once utility recovers, the CPU will switch back to the bypass mode.

t7 : When battery voltage drops to below 26.5V, the CPU will again activate the charger to charge the battery banks (refer to t3 for detailed description).

t8 : Same as t4.

t9 : Due to lack of utility, the CPU will switch to the inverter mode. Since utility is unavailable and it is night time/cloudy, the charging function is in the OFF mode. The AC output relies purely on battery power. So, the battery bank will be depleted rather quickly.

t10 : As the battery discharges below 26.5V and utility remains unavailable and only the solar charger is ON. The battery bank will continue to discharge at a quick pace.

t11 : The battery eventually becomes completely discharged and the inverter shuts down because utility is unavailable. Only when the solar charger current is >3A (day time/sunny) will charging recommence and the battery voltage level will gradually increase.

t12 : Once the battery voltage level has risen to a level capable of restarting the inverter, the inverter will automatically restart. At this time, utility is still OFF, so power to the load is provided by the inverter.

t13 : Utility power is still OFF. If the equipment draws power which is lower than what the solar panel can provide and the solar current is <3A, battery charging will terminate. Inverter will continue to provide power through the battery. The subsequent supply period is subject to capacity of battery and load condition.

Note:

The advantage of the UPS mode is that battery voltage level will be maintained at 90% at all times. This insures that uninterrupted power can be provided to equipment in case of utility failure. Backup period will depend on capacity of battery banks. UPS mode is suitable for areas where AC utility is readily available such as offices and homes.

4.2 Explanation of Energy Saving Mode Control Logic

Figure 4.2 Diagram of energy saving mode control logic

t1: To ensure the battery is at full capacity, when the TN-3000 is turned ON, the CPU will execute the "bypass mode" automatically connecting the AC main to the load. In the meantime, it will activate both the AC charger and solar charger to simultaneously charge the batteries.
t2: When the batteries are full (battery voltage around 28.5V), both the AC and solar charger will be turned OFF by the CPU to prevent overcharging and reducing battery lifetime. The CPU will also switch to inverter mode and the AC electricity provided to the loads will be coming from the batteries.
t3: When the batteries are depleted to around 90% of their capacity (battery voltage around 26.5V), CPU will start up the solar charger but not the AC charger to achieve the goal of energy saving.
t4: If the energy provided by the solar panels is larger than the load requirement, voltage of the battery bank will increase gradually until reaching battery voltage around 28.5V and then the solar charger will shut off to prevent the batteries from overcharging.

t5 : When the capacity of batteries goes down to battery voltage around 26.5V, solar charger will restart and begin charging.
t6 : If the energy provided by the solar panels is lower than consumed by the loads, voltage of the battery bank will decrease gradually to battery voltage around 22.5V. The built-in buzzer will sound to inform the user that battery power is very low.
t7 : If the power consumption of the loads does not decrease and the AC main is normal, the CPU will detect this and the unit will be transferred to "bypass mode." The utility will provide electricity to the loads and charge the battery bank at the same time in order to prevent the unit from shutting off. If the solar current is higher than 3A, the CPU will not activate the AC charger and just let the solar changer charge the batteries to achieve energy saving target.
t8: When there is no AC main, the CPU will shutdown the whole system if the external battery bank voltage is less than 21V in order to prevent over-discharging and reducing its lifetime. After shutdown, the CPU will still provide LED indication so the user knows why the inverter has shut off.

Note:

The advantage of the energy saving mode is that the user only has to add solar panels and solar energy can be harnessed and stored in battery bank for conversion to AC voltage. The user no longer has to rely on AC mains for electricity. The sun can provide all the free electricity needed. Energy saving mode is suitable for areas where AC utility is not readily available such as mountain tops, boats, and vehicles. Even when AC utility is available, the main source of power will still be solar, AC utility will supplement only when necessary. This type of design cuts back the use of paid electricity thus reaching the goal of energy conservation.

6. Protection

6.1 Input Protection

(A) Battery polarity protection: If the battery input is connected in reverse polarity, the internal fuse will blow and the inverter should be send back to us or our authorized distributor for repair.

(B) Battery under voltage protection: When the battery voltage is lower than the pre-set value, the inverter will automatically terminate the output and the "battery low" signal on the display panel will light up. Please refer to table 6.1 for more details about failure signals displayed on the panel.

(C) Battery over voltage protection: When the battery voltage is too high, inverter will automatically terminate the output and the built-in buzzer will sound to inform the user. Please refer to table 6.1 for more details about failure signals displayed on the panel.

! WARNING:

Please choose suitable batteries that is within the input DC voltage range of the inverter (refer to spec).

If the input DC voltage is too low (ex. using 12Vdc battery bank for 24Vdc models), the inverter cannot startup properly.

If the input DC voltage is too high (ex. using 48Vdc battery bank for 24Vdc models), the inverter will get damaged.

(D) Solar charger over current protection: TN-3000 can provide max solar charging current of 30A. If the charging current is too high, the internal fuse will blow and the inverter should be send back to MW for repair.

6.2 Output Protection

(A)Bypass mode: Use no fuse circuit breaker as automatic over current protection.

When over current occurs, the reset button of the circuit breaker on the front panel will pop up and the inverter will shut down. At this time, users should remove the loads, restart the inverter and press down on the reset button of the circuit breaker and the AC output can now be provided normally.

(B) Inverter mode: Under the inverter mode, if any abnormal situation occurs, the display panel will send out failure message (please refer to table 6.1 for failure condition).

(1) OTP: When the internal temperature is higher than the limit value, OTP will activate leading to automatic shutdown. It must be restarted.

(2) Abnormal AC output protection: If the AC output voltage of the inverter is too high or low, the unit will turn OFF and should be restarted again.

(3) AC output short circuit protection: When a short circuit situation occurs at the output or the load increase drastically in a short period of time, the unit will turn OFF and should be restarted again.

(4) Abnormal battery voltage protection: When the battery voltage is too high or low, this protection will be activated. The inverter auto-recovers once the battery goes back to a safe level and the user do not have to restart it.

(5) Output overload protection: When the output is overloaded between 3000W\~3450W, the inverter can continuously provide power for 3 minutes. After that, if the overload condition is not removed, the overload protection will be activated. When the load is higher than 4500W, the overload protection will activate instantly.

7. Installation & Wiring

(A) Wiring for batteries: Wire connection should be made as short as possible and less than 1.5m is highly recommended. Also make sure suitable wires are chosen based on safety requirement and current rating. Too small cross section will result in lower efficiency, less output power, and the wires may also become overheated and cause danger. Please refer to table 7.1 or consult us or our distributor if you have any questions.

Rated current of equipment (amp)	Cross section of wire lead ( mm^2 )	AWGNote
10A ~ 13A 1.25		16	Choosing suitable wires based on the rating of solar panels and distance from the inverter
13A ~ 16A	1.5	14

(C) Installation requirements:

The unit should be mounted on a flat surface or holding rack with suitable strength. In order to ensure the lifespan of the unit, please refrain from operating the unit in high dust or moisture environment. This is a power unit with built-in DC fan. Please make sure the ventilation openings are not blocked and refrain from continuous operation with heavy load in high ambient environment because this may prevent inverter from operating properly and its life span may be affected. We highly recommend that there should be no objects impeding airflow within 15cm of the ventilation openings.

Figure 7.3 Input derating curve

(F) Notes on output loads:

TN/TS-3000 Series can power most equipment requiring an AC source of 3000W. But for certain type of load, the unit may not work properly.

(1) Since inductive loads or motor based equipments needs a large start up current (6\~10 times of its rated current), please make sure this startup current is less than the maximum current capability of the inverter.

(2) When the loads are capacitive or rectified equipments (such as switching power supply), we suggest operating these equipment at no load or light load during power ON. Increase the load slowly only after the TN/TS-3000 has started up to ensure proper operation.
