A solar inverter is a power electronic device or circuitry that changes direct current (DC) to alternating current (AC).Some people will be confused when they choosing the solar inverters,they do not know which kind of power inverters suitable for them,off grid,on gird or hybrid inverter?So we will tell you the difference between off grid on grid and hybrid inverter below:
Off grid solar inverter means the inverter can change DC to AC,it can use the energy from power grid and the batteries to power the electrical loads.For the off grid solar system,battery is mandatory.
However, the hybrid inverter can be used both off grid and on grid, so the battery can be flexibly configured.
For hybrid inverters,normally there are 2 different meanings-off grid inverter with solar charge controller inside or on/off grid in one inverter.
Off grid inverter with solar charge controller inside means there is PWM or MPPT solar charge controller inside the solar inverter,the users can connect the PV input in the solar inverter and check for the PV status on the solar inverter display,easy system connection and checking.
On/off grid in one inverter means the solar inverter can be used on both off grid type and on grid type.
On grid inverter use in on grid solar system,in this solar system,it can not be connected to the electrical loads,all the DC energy generated by the PV will change to AC through the on grid inverter and sent to the power grid directly.For the on grid solar system,there is no need battery.
However, the off grid solar inverter must be equipped with a battery. The solar direct current can be converted into alternating current through the solar charge controller and the off-grid inverter to directly supply power to the load. At the same time, the direct current solar energy can also store electric energy through the battery. When the solar energy cannot be provided, the battery can continue to provide uninterrupted power to the load, and the electronic equipment can still operate normally.Besides, the hybrid inverter can combine the functions of off-grid and on grid inverter.
The above is the difference between off grid on grid and hybrid inverters.
But to be precise, you need to decide what solar inverter to choose according to the power demand of your home, office or different occasions such as cars, RVs and factories.
