Indoor Controller

Working Mode

1,Sunny&Normal Electricity Supply

First the PV panels for the interior specific line-powered electricity generation, excess energy is stored in the ESS.

The mains in standby power mode.

2,Sunny&Grid Power Cut

The PV panels still act as the primary electricity generation unit. If the electricity generated by the PV panels can notmeet the requirement, the ESS will supply the indoor power: When the ESS SOC ≤ 20%, will alarm (once/2sec), when the SOC ≤ 10%, will alarm (once/1sec), and cut off the indoor supply.

3,Weak sunlight&normal electricity

The ESS SOC> 50%, the ESS will supply the indoor power individually, If SOC <50%, switch to power grid supply and start ESS charging.In such cases, the PV panels will not operate.

4,Sunshine Complement&Grid Power Cut

TheESS will supply the indoor power line individually.When the ESS SOC ≤ C will alarm (once/2sec), when the SOC ≤ C ), will alarm once/ 1sec, and cut off the power supply of the indoor.

5,Nightfall

Separate from the ESS to the indoor power line,

when the ESS SoC ≤ 20%, the alarm (1 / 2sec),

when the SoC ≤ 10%, the alarm 1 / 1sec, and cut off the power supply of the indoor.

6,Midnight

Mains supply line for the interior, as well as ESS charged to SoC ≥ 50%.
