MPPT Solar Controller — compact, durable, and designed to maximize the energy you get from your solar panels while protecting your battery bank. Key benefits Improves charging efficiency: MPPT tracking extracts more usable power from your solar panels than basic charge controllers, making better use of available sunlight. Durable, lightweight construction: Aluminum alloy housing provides corrosion resistance and helps dissipate heat without adding bulk. Space-saving design: Small footprint fits into tight installations and is easy to mount or stow. Reliable battery management: Controls and optimizes charging to help maintain battery health and system performance. What it does Tracks the maximum power point of connected solar panels to increase energy harvest. Regulates charging to the battery bank, helping prevent overcharge and undercharge (typical functions of MPPT controllers). Suited for small to medium off-grid and mobile solar setups where efficiency and compact size matter. Important specifications Material: Aluminum alloy Size: 131 x 96 x 55 mm (5.2 x 3.8 x 2.2 inches) Weight: 384 g (13.56 oz) Compatibility and use Compatible with common PV panels and battery banks used in off-grid, mobile, and backup systems (verify voltage and battery chemistry match your system). Typical applications: 1. RV or camper solar setups to increase usable charge and reduce generator runtime. 2. Small off-grid cabins or workshops where panel space is limited and efficiency is important. 3. Marine or remote lighting and battery backup systems that benefit from compact, corrosion-resistant hardware. What’s in the box 1 x MPPT solar controller 1 x User manual (English)
