MPPT Solar Controller — durable, compact, efficient power management for small solar systems Why this controller matters Maximizes energy harvest: The MPPT (Maximum Power Point Tracking) controller optimizes the output of your solar panels so you get more usable power for charging batteries or running DC loads. Built for reliability: A robust aluminum alloy housing provides mechanical strength and helps with passive heat dissipation for stable operation. Easy to install and carry: Compact size and light weight make it simple to fit into tight installations or mobile systems. Key specifications Material: Aluminum alloy — durable construction and improved heat dissipation Product size: 131 x 96 x 55 mm (5.2 x 3.8 x 2.2 inches) — compact footprint for wall- or panel-mounting Weight: 384 g (13.56 oz) — lightweight for portable or mobile use Packing list: 1 x MPPT solar controller, 1 x user manual (English) What it does for you Improves charging efficiency so batteries reach full charge faster and more reliably than non-MPPT controllers Reduces wasted panel energy in varying light conditions (clouds, partial shade, or changing sun angles) Compact, metal design provides a balance of portability and durability for both fixed and mobile installations Compatibility and usage Designed to be used with typical small to medium solar panel and battery setups (panel and battery types depend on your system specifications) Simple to integrate into existing off-grid, backup, or auxiliary power systems Practical use scenarios Off-grid cabin or tiny home: Optimize limited panel area to keep house batteries charged for lighting, small appliances, and devices. RV or boat power system: Save space and weight while improving charge efficiency for leisure batteries during travel and anchoring. Remote equipment or sensor sites: Provide stable battery charging with a compact controller for monitoring equipment, security cameras, or small telecom gear.
