Frequently Asked Questions - EM3500-24L Vevor

How to install the Vevor EM3500-24L inverter?

Mount the device on a non-combustible surface, vertically. Respect ventilation distances. Connect the battery first with a circuit breaker, then AC input, AC output, and finally the solar panels. All wiring must be done by a qualified electrician.

What type of battery to use with this inverter?

Use a lead-acid (AGM, GEL, flooded) or compatible lithium battery with a nominal voltage of 24 V. Recommended capacity is at least 100 Ah. For lithium, you must configure the battery type in program 05.

How to set the power source priority?

Press the ENTER key for 3 seconds to enter setting mode. Use the arrows to select program 01. Choose among Utility First, Solar First, or SBU Priority (Solar, Battery, Utility). Confirm with ENTER.

What to do if the LCD screen shows nothing?

Check that the battery is correctly connected and its voltage is sufficient (at least 23 V to start). Ensure polarity is respected. If the problem persists, recharge or replace the battery.

How to connect solar panels?

Connect the panels in series to achieve an MPPT voltage between 60 V and 500 V. Respect polarity and use a DC circuit breaker between the panels and the inverter. The total panel power must not exceed 4000 W for this model.

What does error code 07 on the screen mean?

Code 07 indicates an overload: the inverter has operated at more than 110% of its rated power for too long. Reduce the connected load or turn off some devices.

Can I use the inverter without solar panels?

Yes, the inverter works as a simple battery/AC converter and AC charger. Solar panels are optional for renewable energy production.

How to configure charge voltage for a lithium battery?

In program 05, select LIB (lithium without communication) or LI2 for Pylontech. Set the bulk charge voltage (program 26) according to BMS specifications, typically 0.5 V below the max charge voltage.

What to do if the inverter constantly switches to battery mode while grid is present?

Check program 01: if Solar First or SBU Priority is selected and the battery is sufficiently charged, the inverter may prioritize battery. Change to Utility First if you want to use grid priority. Also check the return to grid threshold (program 12).

How to clean and maintain the inverter?

Disconnect all power sources before cleaning. Use a dry, soft cloth to remove dust from the casing and screen. Never use liquids. Periodically check connections and fans.

BATTERY EQUALIZATION

The equalization function is added into the charge controller. It reverses the buildup of negative chemical effects like stratification, a condition where acid concentration is greater at the bottom of the battery than at the top. Equalization also helps to remove sulfate crystals that might have built up on the plates. If left unchecked, this condition, called sulfation, will reduce the overall capacity of the battery. Therefore, it is recommended to equalize the battery periodically.

- How to Apply Equalization Function

You must enable the battery equalization function in the monitoring LCD setting program 33 first. Then, you may apply this function in the device by either one of the following methods:

1. Setting equalization interval in program 37.
2. Activating equalization immediately in program 39.

- When to Equalize

In float stage, when the set equalization interval (battery equalization cycle) is reached, or equalization is activated immediately, the controller will start to enter the Equalize stage.

● Equalize charging time and timeout

In the Equalize stage, the controller will supply power to charge the battery as much as possible until the battery voltage rises to the battery equalization voltage. Then, constant-voltage regulation is applied to maintain the battery voltage at the battery equalization voltage. The battery will remain in the Equalize stage until the set battery equalized time is reached.

However, in the Equalize stage, when the battery equalized time expires and the battery voltage does not rise to the battery equalization voltage point, the charge controller will extend the battery equalized time until the battery voltage achieves the battery equalization voltage. If the battery voltage is still lower than the battery equalization voltage when the battery equalized timeout setting is over, the charge controller will stop equalization and return to the float stage.

SETTING FOR LITHIUM BATTERY

Lithium Battery Connection

If choosing a lithium battery for the inverter, you are allowed to use only the lithium battery that we have configured. There are two connectors on the lithium battery: the RS485 port of the BMS and the power cable.

Please follow the steps below to implement the lithium battery connection:

1). Assemble the battery terminal based on the recommended battery cable and terminal size (same as lead-acid, see section Lead-acid Battery connection for details). 2). Connect the end of the RS485 port of the battery to the BMS (RS485) communication port of the inverter.

Fig 1

Lithium battery communication and setting

If choosing a lithium battery, make sure to connect the BMS communication cable between the battery and the inverter. This communication cable delivers information and signals between the lithium battery and the inverter. This information is listed below:

• Re-configure charging voltage, charging current, and battery discharge cut-off voltage according to the lithium battery parameters.
• Have the inverter start or stop charging according to the status of the lithium battery.

Connect the end of the RS485 of the battery to the RS485 communication port of the inverter.

Make sure the lithium battery RS485 port connects to the inverter is Pin to Pin. The communication cable is inside the package, and the inverter RS485 port pin assignment is shown below:

Pin number	RS485 Port
PIN1 RS485-B
PIN2 RS485-A
PIN7 RS485-A
PIN8 RS485-B

LCD setting

After connecting, you need to complete and confirm some settings as follows:

1) Select program 05 as the lithium battery type. 2) Confirm the setting values of programs 41/42/43/44/45.

Note: Programs 43/44/45 are only available with successful communication; they will replace the functions of programs 12/13/29, and at the same time, programs 12/13/29 become unavailable.

LCD Display

If communication between the inverter and battery is successful, some information will be shown on the LCD as follows:

Item Description LCD display
1 Communication successful icon
2 Max lithium battery charging voltage		Max lithium battery charging voltage is 56.0V.
3 Max lithium battery charging current		Max lithium battery charging current is 40A.
4 Lithium battery discharging is forbidden		Li will flash once every 1 second
5 Lithium battery charging is forbidden		Li will flash once every 2 second
6 Lithium battery SOC(%)		Lithium battery SOC is 63AH and 60%

Setting for PYLON US2000 lithium battery

1). PYLONTECH US2000 lithium battery setting:

Dip Switch: There are 4 Dip Switches that set different baud rates and battery group addresses. If a switch position is turned to the "OFF" position, it means "0". If a switch position is turned to the "ON" position, it means "1".

Dip 1 is "ON" to represent the baud rate 9600.

Dip 2, 3, and 4 are reserved for the battery group address.

Dip switches 2, 3, and 4 on the master battery (first battery) are used to set up or change the group address.

NOTE: "1" is the upper position and "0" is the bottom position.

2). Installation process

Step 1. Use the RS485 cable to connect the inverter and lithium battery as shown in Fig 1.

Step 2. Switch on the lithium battery.

Step 3. Press for more than three seconds to start the lithium battery; power output is ready.

Step 4. Turn on the inverter.

Step 5. Be sure to select battery type as "Li2" in LCD program 5.

If communication between the inverter and battery is successful, the battery icon on the LCD display will light up.
