300W -1200W 12V 24V power inverter charger MI Series

The MI series offers a cost-effective solution for backup power systems and solar energy installations of various sizes, with power outputs ranging from 500W to 1200W. These inverters are the choice for those who seek budget-friendly power solutions without compromising on reliability. Their wall-mounted design adds to the practicality of installation, ensuring seamless integration into your projects.



Though the cost of an inverter is less than 15% of the total amount in a power system, without it, the whole system doesn't work. An Inverter is one of the most important pieces of equipment in power systems including solar power systems and UPS backup systems. It's a device that converts direct current(DC) electricity to alternating current(AC) electricity for most home appliances use.

The MI series power inverters output a pure sine wave similar to the waveform of the grid power. In a pure sine wave, the voltage rises and falls in a smooth fashion with very low harmonic distortion and cleaner utility-like power. This gives users stable enough power to operate tools, air conditioners, fans, lights, computers, and other electronics without any interference. Pure sine wave inverters are in many cases more efficient, allowing users to use less energy and allow for more device capability. The main advantage of pure sine wave inverters is that they are used to operate sensitive electronic devices that require high quality waveform with little harmonic distortion. Almost every electronic device could be powered using a pure sine wave inverter.



The inverter charger comes equipped with two working modes that can be changed using a set.

Utility Priority or AC First

Under this setting, once the inverter charger is connected to the utility, it will power the loads using the electricity from the shore supply. The inverter charger will start charging the battery bank using the AC source, if necessary. In case of power outages, the system automatically switches to battery-powered mode. 

Application: home backup power systems for somewhere facing power failures some hours for a day. 

Market-oriented: Thailand, Philippines, Nigeria, Senegal, Mali, Cameroon, Lebanon, Pakistan, Haiti, Venezuela, Chile, etc.


Battery Priority or DC first

Under this setting, the inverter charger will provide power using the connected battery bank even when it detects an AC source. When the battery voltage reaches the low voltage setpoint, the inverter will power the loads using the connected AC source but will not charge the battery bank if the charge current is set to 0A. 

Application: renewable energy systems such as wind power systems, solar power systems, transportation vehicles, trucks, etc.

Market-oriented: Good sunshine area or islands. Thailand, Philippines, Nigeria, Senegal, Mali, Cameroon, Lebanon, Pakistan, Haiti, Venezuela, Chile, etc.
