Used Tracer 2210CN 20 A MPPT Solar Charge Controller – Tested & Working

•Model: Tracer 2210CN. •Tested: Verified under load; provides stable charging current. LCD display with clear status and fault indicators. •History: Removed from a fully functional system—only replaced because I upgraded to LiFePO₄ panels and battery, and this unit doesn’t support lithium battery mode.
