ACOPOWER 50 Amp MPPT Solar Charge Controller

The ACOPOWER 50 Amp MPPT Solar Charge Controller (model HY5415A) manages the connection between your solar array and battery bank, using maximum power point tracking to squeeze more usable energy out of your panels. It automatically identifies 12V, 24V, 36V, or 48V DC systems, so it adapts to a wide range of RV, cabin, and off-grid battery setups without manual configuration. The controller works with sealed, gel, and flooded lead-acid batteries as well as LiFePO4 and other lithium chemistries, with adjustable settings for custom battery profiles. A built-in load relay and multiple control modes give you flexibility over how connected loads are managed, and the RS485 port with MODBUS support lets you link up to eight units in parallel for larger systems. Housed in a die-cast aluminum enclosure with a quiet bladeless cooling fan and high-grade insulation, the controller is built to run efficiently in a vented indoor or semi-protected space such as a battery compartment. It ships with a user manual and is backed by a 1-year workmanship warranty from ACOPOWER.
