On Powmr.com you can buy four different types of pure sine wave Inverters:
1.Solar inverter charger:we also called all-in-one inverter/charger, it has built-in PWM or MPPT solar charge controllers, you can directly use solar energy, AC grid, generator Or a combination of several to charge your batteries. It is a very simple inverter, which is widely used in household solar off-grid systems, RVs, motorboats, etc.
2. Power inverters, this kind of inverters are generally used in RVs. They are a DC-AC device. The charging method comes from solar energy. Some of them can also use city electricity to charge the battery for management.
3.Hybrid inverters (on&off grid), this is a new type of hybrid inverter. Through this inverter, you can store solar energy in the battery for use when there is no electricity or when the electricity price is high. The solar power can be sold directly to the grid.
4.Grid tie inverters: Here are some grid tie inverters.
