Squeeze more power from every panel. The Enerdrive EN43520 is a compact, lithium-ready 20A MPPT controller with an integrated LCD—perfect for 4WD, camper, caravan, and marine systems. MPPT actively tracks the true maximum power point so you’ll harvest more energy (up to ~20–30% vs PWM) across changing light, heat, and shading.
Built for Aussie touring: fast tracking, rock-solid protections, and wide PV input headroom (up to 92 V Voc) let you run modern high-voltage panels safely on 12/24 V battery banks. The on-board screen gives instant voltage, current and daily harvest data, while user-selectable charge profiles (including LiFePO₄) protect your battery investment.
Add it to dual-battery setups, canopy builds, or van conversions where space matters and reliability is non-negotiable.
