Replacing MPPT with direct PV

Jan 02, 2024

So essentially these researchers have discovered what the RV community has been doing for years. If your battery is small, you can use Vmpp=18V panels to directly (or via simple PWM) charge batteries and rely on the BMS to cut off ≥ 100% SOC. All other scenarios are not feasible because the typical PV panel has a Vmpp of 36-37V and thus are not suitable for direct battery coupling.
