Renogy Rover 20A MPPT Solar Charge Controller
Overview
The Rover 20A is an MPPT solar charge controller designed for small off-grid systems. It automatically detects 12V or 24V systems, improves energy harvest with high-efficiency tracking, and offers multiple protections and flexible load control. An optional Bluetooth module and a remote temperature sensor make monitoring and fine-tuning simple.
Benefits
- Get more usable power from the same panels — MPPT tracking increases energy capture so your batteries charge faster and last longer.
- Less worry about weather or temperature — the external temperature sensor and temperature compensation help prevent over- or under-charging across seasons.
- Protect your system automatically — built-in electrical protections reduce the risk of damage and downtime.
- Monitor and control remotely — Bluetooth compatibility and multiple load modes let you check status and adjust settings without being at the controller.
- Simpler installs and maintenance — included mounting brackets and clear wiring instructions make setup straightforward.
Features
- Maximum Power Point Tracking (MPPT) with up to 99% tracking efficiency.
- Automatic system voltage detection: 12V / 24V.
- Rated charge current: 20A.
- Works with PV input voltages up to 100 VDC.
- Supports max PV input power: 260W (12V system) or 520W (24V system).
