Main purpose of this MPPT inverter is to convert harvested energy from PV modules directly (without battery) into heating coil of water tank (or similar appliance).
The inverter optimize harvested DC energy via MPPT algorithm, invert it into AC with rectangular wave with 50Hz frequency.Direct PV connection vs. installation with MPPT inverter:
The biggest advantage of the MPPT inverter can be tracked mostly while the weather is unstable, cloudy or during a sunrise and sunset. That's when to voltage drops because of constant current consumption but lower PV module's power.
With the inverter you can use any common water tank with AC input.
There is several ways of connection. See following example diagrams:
Single coil water tank with HDO switch
Dual coil water tank
