DC to AC solar power inverter is 50000 watt high power, no battery storage system, pure sine wave AC output, wide input voltage can be set according to customers' requirement. Powerful protection fuctions make its service life up to 15-20 years or more.
Pure Sine Wave Off Grid Solar Inverter Features
- Two kinds of start mode: Step-down voltage start and variable frequency start. Customers can set start mode according to the type of their load.
- The output voltage can be set between -40 % to +20 % of rated voltage. And the output voltage is very accuracy ±1%.
- Pure sine wave output. With good dynamic response less than 50MS, waveform distortion rate smaller, higher conversion efficiency and stable output voltage.
- Adopts black pure aluminum radiator, which confirms the best radiating performance.
- Powerful data display function. LCD can display the DC input voltage, output frequency, phase voltage, phase current, AC bypass input voltage, output power KWH, time and date, temperature, fault code display.
- Wide input voltage can work without battery and solar charge controller, save more cost and with MPPT wide voltage input function, maximum use of solar power.

Tips: PV solar inverters must be placed in an air-circulated space
For every 10 °C increase in ambient temperature, the life of the electronic device is halved. For the long-term exposure of this type of PV solar inverter in the hot sun, the internal temperature of the inverter will increase greatly, seriously affecting the life of the key components of the inverter. In order to protect the internal components, the inverter will derate the operation. Even if the temperature is too high, the soalr inverter temperature will be faulty. It is recommended to add a sunshade to the PV inverter to avoid sun exposure.
When installing outdoors, the PV soalr inverter should be equipped with a rain-proof sun protection awning to avoid direct sunlight and rain. Do not expose the inverter directly to the sun or other heat sources. Leave enough space for it to be installed and moved to the inverter. A minimum of 50cm of space is required around the inverter that enters and exits the wind. The soalr inverter that enters and exits the wind from the left and right is the air entering from the side, and the space distance of more than 100cm is left on both sides.
The PV soalr inverter must be placed in a space where air is circulated. The cooling method of a power inverter is divided into forced air cooling and natural heat dissipation. The power inverter itself is a heat source. All the heat should be emitted in time and cannot be placed in a closed Space, otherwise the temperature will rise higher and higher.
