When grid is on, the EPS terminal is connected to grid terminal inside inverter by a passthrough relay. so the hybrid inverter will bypass the interactive inverter AC to grid in this situation. The spec of the passthrough relay is 90A.
When grid is off, the hybrid inverter will work as a power source for the grid interactive inverter to synchronize and feed power to the micro-grid. The loads will be first supplied by solar power. If solar panels are generating more power than load consumption, the excess solar power will be stored to the battery. When solar power exceeds the sum of load power and max battery charging power, e.g. when battery is nearly full. The inverter will signal the grid interactive inverter to reduce power via the frequency shifting power reduction mechanism, thus to maintain the balance of generation and consumption of the microgrid system.

Users need to enable AC coupling function when they connect existing on grid system to EPS terminal.

4. Operation Guide
4.1 Operation Mode and Function
The inverter has different working mode to meet customers’ various demands, the working modes are as below:
4.1.1 Self-usage Mode (Default)
In this mode, the priority order of load supply source is Solar>Battery>Grid. The priority order of solar power usage is Load>Battery>Grid.
Application Scenarios Self consumption mode will increase self consumption rate of solar power and reduce the energy bill significantly Related Settings Effective when Charge Priority , AC Charge, and Forced discharge are disabled Example

Smart Load: This function is to make the Gen input connection point as an load connection point, if you enable it, inverter will supply power to this load when the battery SOC and PV power is above a user setup value. e.g. Smart load start SOC=90%, Smart load end SOC=85%, Start PV power=300W, it means: When the PV power exceeds 300W, and battery system SOC gets to 90%, Smart Load Port will switch on automatically to supply the load which is connected on this side. When the battery SOC<85% or PV power<300w, the Smart Load Port will switch off automatically.

Standby: Is for users to set the inverter in normal status or in standby status. In Standby status, the inverter will stop any charging or discharging operation, as well as solar-feed-in.

Restart inverter: Restart the system, please note the power maybe interrupted when restart
Feed-in Grid: Is for users to set zero export function. If exporting solar power is not allowed, users need to disable “Feed-in Grid” option. If users’ utility meter will be tripped with even a little solar export, “Fast zero export” can be enabled thus the export detection and adjustment will take place every 20mS, which will effectively avoid any solar power being exported. If export is allowed, users can enable “Feed-in Grid” and set a maximum allowable export limit in “Feed-in Power(kW)”.

Offgrid output: Is for users to set if the inverter provides backup power or not when the grid is lost. If users want load to be seamlessly transferred to inverter backup power, “Seamless switch” must be enabled. If customers don’t have battery installed yet, but still wish to have inverter backup power with only solar panels connected, “PV Grid Off” can be enabled to use solar power to supply load when grid fails or load-shedding happens. Micro-grid: only needs to be set when generator is connected at the inverters grid port. With this option enabled, the inverter will use AC power to charge battery and won’t export any power through grid port if AC power is present at inverter grid port.
Charge last: When users want to use solar power in the order of loads — grid export — battery charging.
AC couple: When you want to use the inverter as an ac coupled model, you can enable
CT direction reversed: When the CT is installed on the wrong direction, installer can modify it by selecting it, no need reconnect. er in the order of loads — grid export — battery charging.
