The scenario
A village water supply uses a 5 kWp solar array with battery storage to run a 3 HP AC pump through an MPPT charge controller and inverter.
What is in this drawing
Read the decisions behind it.
01
Use MPPT controller to optimize PV output and charge 48V battery bank
02
Include battery isolator and pump contactor for safe operation and control
03
Common DC negative rail simplifies grounding while AC output remains isolated
Applicable for off-grid solar water pumping systems with battery backup, especially in rural or agricultural settings.
