Frequently Asked Questions - TS-1500-248B Mean Well

Can the TS-1500-248B charge batteries?

No, the TS-1500 series is an inverter-only model. It does not include an AC charger or solar charger. For battery charging functionality, refer to the TN-1500 series.

How do I set the output voltage and frequency?

Turn off the inverter, connect batteries, remove loads. Press and hold the setting button (using an insulated stick) while turning on the power switch. After a beep, release. Follow the LED indications to select voltage/frequency combination as described in the manual. Press and hold again to confirm.

What is the difference between UPS mode and Energy Saving mode?

In UPS mode, the inverter stays in bypass when utility is available, conserving less energy. In Energy Saving mode, the inverter prioritizes battery power (solar first) to maximize energy savings. The mode is selectable via the front panel button.

What does the 'Saving' LED indicate?

The 'Saving' LED lights up when the inverter is operating in Energy Saving mode and there is no AC output (e.g., during standby). It indicates that the inverter is saving energy by not producing output until needed.

What should I do if the inverter does not produce AC output?

Check that battery voltage is within range (42-60V), wiring polarity is correct, and the circuit breaker is not tripped. Also verify that the power switch is ON. If protection is triggered (overload, over temp, short circuit), remove the cause and restart.

What type of batteries should I use?

Use lead-acid batteries of the same brand and capacity. For a 48V system, recommended capacity is 30Ah to 100Ah. Avoid mixing different battery types or ages.

How long can the inverter run at 1500W?

The inverter can deliver 1500W continuously. It can handle 1750W for up to 3 minutes and 1875W for 10 seconds. Surge capability up to 3000W for 30 cycles (approx. 0.5s). Actual runtime depends on battery capacity.

Can I connect the inverter directly to my vehicle's battery?

Yes, but ensure the engine is running before turning on the inverter if connected directly. This prevents excessive drain on the starting battery. Use appropriate wire size (see manual table).

How do I reset the inverter after a fault?

For overload or over temperature, remove the cause and turn the inverter OFF, then ON again. If the circuit breaker (no fuse breaker) tripped, press the reset button after correcting the fault. For reverse polarity, the internal fuse blows and requires factory service.

Is the TS-1500-248B compatible with remote monitoring?

Yes, it has a communication port on the front panel. Optional monitoring software (available from Mean Well website) can be used to adjust settings and view status via PC. This is optional for TS-1500 (standard on TN-1500).

4. Explanation of Operating Logic

TN-1500 (CPU controlled inverter) is designed to achieve the goal of energy saving 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 or use the monitoring software to switch to the Energy saving mode.

The main difference between 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 Fig. 4.1 for UPS mode control logic). Under the Energy saving mode, the priority of input source chosen is solar panel AC main battery. If available, the CPU will select external solar panels 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 resort. When the capacity of batteries is around 10\~20%, the CPU will remind end users 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-1500 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 the battery lifetime. In the meantime, the system will remain in the "Bypass Mode" and AC electricity provided to the loads is coming from public utility.

t3: At this time period, TN-1500 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 75% of their capacity (battery voltage around 26.5V) the CPU will restart the charger. The CPU will use charging current of 3A as a guide point. When the provided charging current is under 3A, the AC charger will be turned ON (e.g. Night time or cloudy day). As for charging current of over 3A, the solar charger will be turned ON instead.

t4: If the energy provided by the charger is larger than what is consumed by the load, voltage of battery bank will increase gradually until 28.5V is reached then the CPU will be shut off the charger to prevent overcharging. At this point, output load is still supplied by utility.

t5: Since the chargers are in the OFF mode, the battery voltage will gradually decrease to the range of 26.5\~28.5V (floating voltage level). 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 battery charger will be activated to charge the battery bank (refer to t3 for detailed description).

t8: Same as t4.

t9: Due to lack of utility, TN-1500 will switch to the inverter mode. AC charging function will be turned off. Since AC output relies purely on battery power, the battery bank will be depleted rather quickly.

t10: As the battery discharges to below 26.5V and utility remains unavailable. Only the solar charger is turned ON. The battery bank could be depleted rather quickly.

t11: Same as Energy Saving mode.

t12: When solar charger is providing current of larger than 3A, the voltage level of the battery bank will rise slowly. Once the battery voltage reaches inverter mode reactivation level, the inverter will be revived.

4.2 Explanation of Energy Saving Mode Control Logic

Figure 4.2 Diagram of Energy Saving Mode Control Logic

t1: When the TN-1500 is turned on, CPU will execute the "Bypass Mode" automatically connecting the AC main to the load. In the mean time, 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 to prevent overcharging and reducing the battery lifetime. In the meantime, the system will switch to the "Inverter Mode" and the AC electricity provided to the loads will be coming from the batteries.

t3: When the batteries are depleted to around 75% of their capacity (battery voltage around 26.5V), CPU will restart the solar charger but not the AC charger to achieve the purpose of energy-saving.

t4: If the energy provided by the solar panels is larger than the load requirement, voltage of battery bank will increase gradually until reaching 90% capacity (battery voltage around 28.5V) and then the solar charger will be shut off to prevent the batteries from overcharging.

t5: When the capacity of batteries go down to about 75% (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 battery bank will decrease gradually to 20% of its capacity (battery voltage around 22V), the built-in buzzer will be activated and inform the users to take proper action.

t7: If the power consumption of the loads does not decrease and the AC main is normal, CPU will detect this and the unit will be transferred to "Bypass Mode". The utility will provide energy 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 Charger" charge the batteries to achieve the goal of energy-saving.

t8: When lacking AC main, the CPU will shut down the whole system if the capacity of external battery bank is less than 10% (battery voltage around 21V) in order to prevent over-discharging and reducing its lifetime. After shut down, the CPU will provide LED indication to the user know why the inverter has shut off.

Note: Battery voltage under 18V is considered as over-discharged or defective, which requires special treatment or replacement. When battery voltage is etected under 18V, the AC charger will not operate to prevent damaging the batteries.

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 MEAN WELL for repair.
(B)Battery Under Voltage Protection: When the battery voltage is lower than the preset value, the inverter will automatically terminate the output and "Battery Low" signal on the front panel will light up. Please refer to Table 6.1 for more detail about the failure signals displayed through the "Load Meter."
(C)Battery Over Voltage Protection: When the battery voltage is too high, inverter will automatically terminate the output and the built-in buzzer will activate to inform the users. Please refer to Table 6.1 for more detail about the failure signals displayed through the "Load Meter."

! WARNING:

Please choose suitable batteries that is within the rated input DC voltage of TN/TS-1500 (refer to the SPEC). If the input DC voltage is too low (ex. using 12Vdc battery bank for 24Vdc input models), TN/TS-1500 can't be started up properly. If the input DC voltage is too high (ex. using 48Vdc battery bank for 24Vdc input models), TN/TS-1500 will be damaged!

(D) Solar Charger Over Current Protection: The maximum charging current of the built-in solar charger is 30A. If the charging current is too high, the internal fuse will blow and the inverter should be send back to MEAN WELL for repair.

6.2 Output Protection

(A) Bypass Mode: Uses "No Fuse Breaker" as automatic over current protection. When over current occurs, the 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 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 front panel will send out failure messages through the "Load Meter" (Please refer to Table 6.1).
(1) Over Temperature Protection: When the internal temperature is higher than the limit value, the "Over Temperature Protection" will be activated. The unit will automatically turn off and should be restarted again.
(2) AC Output Abnormal Protection: When the AC output voltage of the inverter is too high or too 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 side of the inverter or the load increase greatly in a short period of time, the unit will turn off and should be restarted again.
(4) Battery Voltage Abnormal Protection: When the battery voltage is too high or too low, this protection will be activated. The inverter will auto-recover once the battery voltage go back to a safe level and users do not need to restart it.
(5)Output Overload Protection: When output is overloaded between 1500W \~ 1750W, 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 1875W, the overload protection will activate instantly. For these overload protections, once activated, you should reset the unit.

(F) ⚠️ Notes on Output Loads:

TN/TS-1500 Series can power most of equipments that need an AC source of 1500W. But for certain specific type of load, the unit may not work properly.

(1) Since inductive loads or motor based equipments need a large start up current (6\~10 times of its rated current), please make sure this start up current is less than the maximum current capability of the inverter.
(2) When the output are capacitive or rectified equipments (such as switching power supply), we suggest operating these equipment at no load or light load condition. Increase the loads slightly only after the TN/TS-1500 has started up to ensure proper operation.

8. Failure Correction Notes

TN/TS-1500 should serviced by a professional technician. Improper usage or modification may damage the unit or result in shock hazard. If you are not able to clear the failure condition, please contact Mean WELL or any of our distributors for repair service.

Status Possible	Reasons Ways to Eliminate
No AC output voltage	Abnormal input	Check the AC or DC input sources. Make sure the voltage is within the required range.
	No input (battery, AC main or solar energy)	Make sure the wiring and polarity is correct.
	Over temperature protection	Make sure that the ventilation is not blocked or whether the ambient temperature is too high. Please derate output usage or reduce the ambient temperature.
	Overload protection	Make sure the output load does not exceed the rated value or the instantaneous start up current is not too high (for inductive or capacitive loads).
	Short circuit protection	Make sure the output is not overloaded or short circuit
Discharging period of batteries is too short	Batteries are aging or broken	Replace the batteries
	Battery capacity is too small	Reconfirm the specification and enlarge the battery capacity as suggested
	Malfunction of the charger (no charging voltage)	Repair required. Please send it back to us or any of our distributors
Fan does not spin	Clog with foreign objects R	Remove the foreign objects
	Malfunction of the fan	Repair required. Please send it back to us or any of our distributors
