Pure Sine Wave Output

The electrical waveform output of PV1800PK is a pure sine wave, which has the same quality as utility and/or domestic power. This type of waveform is suitable for most all electrical devices, appliances and tools. This pure sine wave unit provides more capabilities than modified sine wave inverters, because it is a cleaner form of power. The pure sine wave also effectively reduces the noise produced while using appliances.

Wifi communication

you can download this app on your cellphone and monitor the whole system, you will know how much electricity the system generate and sell to utility.

4-5KVA Parallel function

Customer can use 2pcs or 3 pcs inverters to expand the system capacity. Maximum 3pcs parallel to single phase or three phase.Parallel kit picture as below:

Charging algorithm

3-Step (Flooded Battery, AGM/Gel/Lithium Battery),4-Step(LI)

Monitoring system

With USB can connect with computer monitoring the working stage and the data of PV, AC and battery. LCD setting is also available in computer.

Utility-Tie state

PV energy is charger into the battery and utility provide power to the AC load

Charge state

PV energy and grid can charge batteries.

Bypass state

Error are caused by inside circuit error orexternal reasons such as over temperature,output short circuited and so on.

Off-Grid state

The inverter will provide output powerfrom battery and PV power
