With Modbus card II and energy meter, hybrid inverter can be
easily integrated into the existing household system. For details
please refer to Modbus card II manual.
1) For single inverter application: Equipped with Modbus card
II, hybrid inverter is connected to energy meter with RS485
communication port. It’s to arrange self-consumption via
Modbus card to control power generation and battery
charging.
If using a sealed lead acid battery, please set up the max.
charging current according to below formula:
The maximum charging current = Battery capacity (Ah) x 0.2
For example, if you are using 125 Ah battery, then, maximum
charging current is 125 x 0.2=25 (A). Please use at least 25Ah
battery because the settable minimum value of maximum
charging current is 5A. If using AGM/Gel or other types of
battery, please consult with installer for the details.

2) For three-inverter application: Equipped with Modbus card
II, three hybrid inverters are connected to energy meter with
RS485 communication port. As a control center, Modbus
server will control power generation and battery charging of
three inverters via Modbus card for successful
self-consumption.
