Maximize your solar harvest with the PowMr MPPT Solar Charger Controller, delivering smart, efficient power management for 12V/24V systems.
- Available in 25A, 35A, and 45A models for 12V/24V systems, letting you match your battery bank and solar array.
- MPPT tracking up to 99.9% and peak conversion up to 97%, with a 100V PV input limit and model‑dependent input power (12V: 300/420/540W; 24V: 600/840/1080W).
- Adaptive Boost Charging automatically tailors boost duration per cycle to fully charge without overcharging, protecting battery life.
- 3-stage charging algorithm for efficient charging across 12V/24V, compatible with lead-acid and lithium chemistries; IP32, -35°C to 45°C, compact frame.
