3.2 Application Scenarios

Supported Grid Types

WARNING

• The PV system is not suitable to connect equipment that relies on a stable power supply,

such as medical equipment to sustain life. Ensure that no personal injury is occurred when

the system is disconnected.

• Avoid loads with high starting current like high-power water pumps in the PV system.

Otherwise, the o-grid output may fail due to excessive instantaneous power.

• Do not start the BACK-UP function if the PV system is not congured with batteries.

Otherwise, the manufacturer shall not be liable for related system risks.

• Factors such as: temperature, humidity, weather, etc. may limit the battery's current and

aect its loading capacity.

• The inverter supports UPS, and the switching time of UPS is less than 10ms. The UPS

function may fail to start if the BACK-UP load capacity exceeds the rated power of the

inverter.

• When single overload protection occurs, the inverter can restart automatically; however,

the restarting time will be extended if it happens several times. For a faster restarting, try it

via app.

• Normal household loads can be supported when the inverter is in back-up mode. Accepted

loads as below:

• Inductive loads: 1.5P non-inverter air conditioner

• Capacitive loads: total power ≤ 0.6 times of the inverter’s rated output power.

For the grid type with neutral wire, the voltage between the neutral wire and the ground must

be less than 10V.
