Can I connect a 12kWp solar system to the EP800, even if it exceeds the PV

input power? Will the EP800 automatically adjust the PV input current?

Whether you can connect a 12kWp solar system to the EP800 depends on the

voltage of your solar setup. The EP800 can work with solar systems that have an

open-circuit voltage ranging from 150V to 500V. It's able to accommodate two

PV inputs, with a total power of 9,000W (3kW for PV1 and 6kW for PV2). The

EP800 can automatically adjust the input current to stay within these limits,

but it won't exceed 12.5A for PV1 and 25A for PV2.

Can it charge and discharge at the same time?

Yes. The EP800 supports pass-through charging.

Can my household appliances be powered by solar panels while they are

charging the battery?

Yes, in the "Self-consumption" mode, the EP800 prioritizes solar power for

running household appliances, and any extra energy is used to charge the

battery.

How does the EP800 power my household appliances? Does it use solar power

ﬁrst and then switch to grid power when needed?

You can conﬁgure the EP800 to operate in "Self-consumption" mode. In this

mode, the EP800 prioritizes solar energy for running household appliances. If

there's not enough solar power available, the EP800 combines it with stored

energy from the battery to power your appliances. Only if there's still not

enough power, it will draw electricity from the grid to meet your demand.
