Wiring Connection

The cable size of each inverter is shown below

Recommended battery cable and terminal size for each inverter:

WARNING: Be sure the length of all battery cables is the same. Otherwise, there will be voltage difference between inverter and battery and it might cause mal-function of the working inverters in parallel.

Recommended AC input and output cable size for each inverter:

You need to connect the cables of each inverter together. Take the battery cables for example: You need to use a connector or bus-bar as a joint to connect the battery cables together, and then connect it to the battery terminal. The cable size used from joint to battery should be X times of cable size in the tables above. “X” indicates the number of inverters connected in parallel.
Regarding cable size of AC input and output, please also follow the same principle.

Product Instruction

This hybrid PV inverter can provide power to connected loads by utilizing PV power, utility power and battery power.

Depending on different power situations, this hybrid inverter is designed to generate continuous power from PV solar modules (solar panels), battery, and the utility. When MPP input voltage of PV modules is within acceptable range (see specification for the details), this inverter is able to generate power to feed the grid (utility) and charge battery. This inverter is only compatible with PV module types of single crystalline and poly crystalline.

Do not connect any PV array types other than these two types of PV modules to the inverter. Do not connect the positive or negative terminal of the solar panel to the ground.
