1. The starting power of inductive load electrical appliances shall be at least three times of the rated power of the electrical appliances. If the starting power exceeds the inverter power, the inverter may be damaged. Please select a suitable model before purchasing.
2. Please connect the circuit correctly according to the instructions, and install switches for each circuit.
3. Starting sequence: first turn on the battery switch, start the inverter, and turn on the PV, mains and load switches.
4. Shutdown sequence: turn off the switches of load, PV and mains, turn off the inverter, and finally turn off the battery.
Please find an electrician to install the inverter. Installing it yourself can cause danger or damage to the equipment.

Dual output function description:
The main and secondary outputs are used in normal condition. But in the following two conditions, the main output is disconnected and only the secondary output is retained:
– when there is no solar power input and mains power input;
– when the battery voltage is lower than 44V (the minimum can be set to 41V, and the maximum can be set to 46V);
Advantages of dual output:
In a power generation system using lithium batteries for storage, when the inverter is under full load or high-power load, due to the characteristics of lithium batteries, the battery voltage tends to drop too quickly, which shall make the battery voltage too low and disconnect the battery while the battery bank still keeps 50% of rated power.
With the dual output function, user can connect some important loads to the secondary output. When the battery voltage is low (typically lower than 44V, with a minimum setting of 41V), the inverter shall disconnect the main load and ensure the output of the secondary load, which can extend the operation time of the secondary load.
