Battery Connection
CAUTION: For safetyoperation and regulation compliance, it’s requested to install a separate DC over-current
protector or disconnect device between battery and controller. It may not be requested to have a disconnect device in
some applications, however, it’s still requested to have over-current protection installed. Please refer to typical
amperage in below table as required fuse or breaker size.
Ring terminal:
WARNING! All wiring must be performed by a qualified person.
WARNING! It's very important for system safety and efficient operation to use
appropriate cable for battery connection. To reduce risk of injury, please use the
proper recommended cable and terminal size as below.
Note: For the lead acid battery, the recommended charge current is 0.2C(C-battery capacity). Please follow below steps to
implement lead-acid battery connection:
1. Assemble battery right terminal based on recommended battery cable and terminal size.
2. Connect all battery packs as units requires. It’s suggested to connect at least 550Ah capacity battery for 48V/120A model.

Insert the ring terminal of battery cable flatly into battery connector of controller and make sure the bolts are tightened with
torque of 2-3Nm. Make sure polarity at both the battery and the controller is correctly connected and ring terminals are tightly
screwed to the battery terminals.
WARNING: Shock Hazard
Installation must be performed with care due to high battery voltage in series.
CAUTION!! Do not place anything between the flat part of the controller terminal and the ring
terminal. Otherwise, overheating may occur.
CAUTION!! Do not apply anti-oxidant substance on the terminals before terminals are connected
tightly.
CAUTION!! Before making the final DC connection or closing DC breaker, be sure positive (+) must

If choosing lithium battery for the controller, you are allowed to use the lithium battery only which have configured. There're
two connectors on the lithium battery, RJ45 port of BMS and power cable.
Please follow below steps to implement lithium battery connection:
1. Assemble battery ring terminal based on recommended battery cable and terminal size (same as Lead acid, see section
Lead-acid Battery connection for details) .
2. Insert the ring terminal of battery cable flatly into battery connector of inverter and make sure the bolts are tightened with
torque of 2-3Nm. Make sure polarity at both the battery and the inverter/charge is correctly connected and ring terminals are
tightly screwed to the battery terminals.
3. Connect the end of RJ45 of battery to the communication port of the controller.
4. The other end of RJ45 insert to battery comm port.
Note: If choosing lithium battery, make sure to connect the BMS communication cable between the battery and the controller.
You need to choose battery type as “lithium battery”
Lithium battery communication and setting
In order to communicate with battery BMS, you should set the battery type to “LI” in Program 2. Then the LCD will switch to
Program 21, which is to set the protocol type. There are several RS485 protocols in the controller which can match some
customized battery, Please consult with supplier first before you choosing the battery model.
1. Connecting the communication port between the controller and battery
Make sure the lithium battery BMS port connects to the controller is Pin to Pin, the controller communication port pin
assignment shown as below (“COM” port on the controller, support RS485 or CAN protocol).

2. LCD setting
To connect battery BMS, need to set the battery type as “LI” in Program 02. After set “LI” in Program 02, it will switch to
Program 21 to choose battery type. There will be some options under Program 21.

When the battery type set to Li, the setting option 07 will change to display percent.
Note: When the battery type set as “Li”, the Maximum charge current can’t be modified by the
user. When the communication fail , the inverter will cut off output.
Inverter Connection
Some specific off grid inverters and this controller can communicate to summarize data. Make sure the inverter connect to the
controller Pin to Pin as below by communication port (“COM” port on the controller).

Battery Equalization
Equalization function is added into 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’s recommended to equalize battery periodically.
How to Apply Equalization Function
You must enable battery equalization function in monitoring LCD setting program 10 first. Then, you may apply this
function in device by either one of following methods:
1. Setting equalization interval in program 14.
2. Active equalization immediately in program 15.
When to Equalize
In float stage, when the setting equalization interval (battery equalization cycle) is arrived, or equalization is active
immediately, the controller will start to enter Equalize stage.

18
Equalize charging time and timeout
In Equalize stage, the controller will supply power to charge battery as much as possible until battery voltage raises to
battery equalization voltage. Then, constant-voltage regulation is applied to maintain battery voltage at the battery
equalization voltage. The battery will remain in the Equalize stage until setting battery equalized time is arrived.
However, in Equalize stage, when battery equalized time is expired and battery voltage doesn’t rise to battery equalization
voltage point, the charge controller will extend the battery equalized time until battery voltage achieves battery equalization
voltage. If battery voltage is still lower than battery equalization voltage when battery equalized timeout setting is over, the
charge controller will stop equalization and return to float stage.
