What it does and why you need it - MPPT solar charge controller that maximizes energy harvest from your solar panels by continuously tracking the panels’ maximum power point. Ideal where you want more usable energy from the same panels and more consistent charging performance in changing light conditions. Key benefits - Improved charging efficiency: MPPT tracking extracts more power from solar panels than basic controllers, helping batteries charge faster and operate more reliably. - Durable, lightweight housing: Precision aluminum alloy construction provides structural strength, corrosion resistance, and effective heat dissipation while keeping weight low. - Compact footprint: Small physical size makes it easy to mount inside enclosures, on walls, or in vehicles without occupying much space. Primary functions and compatibility - Regulates and optimizes solar panel output for charging battery systems in PV setups (functions as the control interface between solar panels and the battery/storage side). - Suitable for integration into small to medium off-grid solar systems and portable solar installations. Compatible with standard solar PV arrays and battery banks used in typical solar setups. Important specifications - Material: Aluminum alloy (durable, lightweight) - Product size: 131 x 96 x 55 mm (5.2 x 3.8 x 2.2 inches) - Weight: 384 g - Packing list: 1 x MPPT solar charge controller, 1 x user manual (English) Practical use scenarios - Small off-grid cabin: Improve daily charge efficiency so lights, appliances, and sensors run longer from the same solar array. - RV or campervan: Fit the compact controller into limited space to better capture energy while on the move or parked in variable sunlight. - Remote equipment or workshop: Mount inside an equipment cabinet to provide reliable, optimized charging for battery-backed systems. Why this product stands out - Combines MPPT performance with a corrosion-resistant aluminum alloy body and a compact, serviceable size. The included English user manual supports straightforward setup and integration into common solar PV configurations.
