Five modes of operation, working Mode(optional): 1.AC Input Priority; 2.Battery Priority; 3.ECO Mode; 4.Generator Mode; 5.Unattended Mode.High transfer efficiency is above 90%, , complete isolate surge interference of input & output’s voltage and current, Impact resistance, super load capacity, built-in AVR stabilizer, continuous stable pure sine wave output.Protections: AC input over voltage protection/AC Input low voltage protection/Low battery alarm/High battery alarm /Over temperature protection/Over load protection Short Circuit protection (1s after fault)
/Back feeding protection

This Solar inverter is able to charge the battery bank when AC power & Solar power are connected to the inverter.

This inverter can ONLY work with 12V battery system.

The inverter CAN NOT can in parallel.

Battery MUST BE connected first

1000 watt is continuous output power, peak power is 3000W

Package included:

1*1200W12V Solar Inverter1*User Manual

Note: Different types of loads have different starting impulse currents. Customers need to select the appropriate inverter model according to the actual equipment power, current, and load characteristics.

What kind of the inverter is suitable for your appliances?

Pls know that load is divided into resistive load and inductive load .If you need the inverter to run the resistive load (like laptop, TV, electric cooker ), please choose the inverter with continuous power higher than the appliance’s rated power. And it is best to use 80% of the rated power. If you use microwaves, water pumps, air conditioners and other appliances with motors or compressors ,please choose the inverter whose continuous power is 3-10 times higher than your appliances.

Working Mode Setting:

1. AC/Line priority mode — always use ac power/solar panel as priority input, provide ac output, and automatically charge the battery.

2. Battery priority mode — Priority should be given to battery power supply. After low voltage protection, the battery will be transferred to ac grid power supply. When the battery is full, the battery will be transferred back to battery power. For example, 12V system, when the battery voltage ≥13V, it will transfer to battery power, when the battery voltage ≤ 10.5v, switch to the mains mode, provide ac output, and automatically charge the battery. Switching voltage is be adjusted.

3. ECO Mode—Load < 10% automatic sleep and stop output, load > 10% automatic boot back to normal inversion.

4. Generator mode — The generator is connected to the AC input of the inverter, and the output is stabilized through AVR while the battery is recharged.

5. Unattended Mode—When the battery is low voltage, the inverter goes into standby state(Power saving state). When the battery restores the voltage value set by yourself (such as solar charging), the inverter will restore the normal output of the inverter, and realize unattended full automatic operation!
