Where to Buy?


Suitable for charging lithium battery

Save electricity bill

It is hybrid energy storage inverter, can feed power into grid, to use free solar power help you save electricity bill.

Parallel function up to 3 units

Built-in MPPT Solar Charge Controller

By maximizing solar energy harvesting under a wider variety of environmental conditions, MPPT technology helps the system extract as much electricity as possible for more effective energy storage. It is ideal for use in a wide-range of residential, light commercial, agricultural, community and other applications that can benefit from better yields through more advanced charge controller technology.

We make you an excellent shell

This inverter is also built to withstand reasonable heat and temperature fluctuations because of its over-temperature protection and dual thermally-controlled fans. And it’s protected from humidity or airborne dust and dirt by virtue of its marine-coated (or “conformal-coated”) boards. This inverter provides the reliability needed in any business or residential emergency backup power applications.

Active Cooling System

2 large cooling fans are adapted to ensure the inverter is additionally ventilated. As soon as the device produces more heat than can be dissipated through the enclosure, internal fans are switched on creating an air flow through the cooling ducts of the enclosure. The fans are RPM controlled, i.e. it increases its speed with increasing temperature.

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.



In comparision with pure on-grid solar inverter, PH3000 model can not only feed-in power to grid, but also store PV power to battery, and power loads directly. Combining the function of inverter, on-grid, MPPT solar charger, and battery charger to offer uninterruptible power support. Its comprehensive LCD display offers user configurable and easy accessible button operation, such as battery charging current, AC/solar charging priority, and acceptable input voltage based on different appications.
