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

4.1.4 Grid peak-shaving Function
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.
Note:
If you enable the Smart load function, it’s
forbidden to connect the generator at the
same time, otherwise the device will be
damaged!

4.2.2 Setting Parameters
Clicking on the gear icon at the bottom of the screen, you'll get into the parameter setting page of the inverter.
a. Basic settings
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)”.
