​Using a battery or another power source, a 2000W power inverter may transform DC (direct current) electricity into AC (alternating current) electricity, usually at a voltage of 120VAC or 240VAC. When you don't have access to an AC power outlet, you can use this to power appliances and gadgets that need AC electricity.

The market is flooded with excellent 3000W pure sine wave inverters. Among the greatest choices are:

Modified sine wave inverters should avoid "inductive loads". In layman's terms, high-power electrical products made by applying the principle of electromagnetic induction, such as motors, compressors, relays, fluorescent lamps, etc. Such products require a much larger starting current (about 5-7 times) than the current required to maintain normal operation when starting.

The MPPT solar controller should be more complicated, and the cost is higher. The price is usually several times or even dozens of times of the PWM solar controller. The greatest energy. The MPPT controller can detect the power generation voltage of solar panels in real time and track the maximum voltage current value (VI), so that the system is charged to the battery with a maximum power output.

The electrical structure of the PWM solar controller is relatively simple, mainly consisting of a power main switch, a capacitor, one drive plus a protection circuit, actually equivalent to a switch, connecting the components and batteries together, the voltage of the component is pulled down A voltage close to the battery pack.

The solar controller is mainly used in the solar access mesh power generation system, which can automatically control the multi-channel solar panels to charge the battery, coordinate the solar panel, battery, load operation, monitor the charging state, showing the solar panel to charge the battery.
