Squeeze more power from every panel. The Enerdrive EN43520 is a compact, lithium-ready 20A MPPT controller with an integrated LCD - suited to 4WD, camper, caravan and marine systems. MPPT actively tracks the true maximum power point, so it harvests more energy than a PWM controller across changing light, heat and shading.
Wide PV input headroom (up to 92V Voc) lets you run modern high-voltage panels on 12V or 24V battery banks. The on-board screen gives instant voltage, current and daily harvest data, and user-selectable charge profiles (including LiFePO4) protect the battery.
Suits dual-battery setups, canopy builds and van conversions where space matters.
