Solar Rex’s 80Ah Solar Charge Controller combines versatility and power for large-scale energy projects. Available in MPPT (up to 98% efficiency) and PWM (cost-effective) variants, it supports 12V/24V/36V/48V systems with a massive 80A charging current and 3,840W PV input (48V). The MPPT model uses real-time tracking to extract 30% more energy than PWM, while both feature 4-stage charging (bulk, boost, float, equalization) for lithium, LiFePO4, and lead-acid batteries.
An intuitive LCD displays real-time metrics (current, voltage, errors), and dual USB ports (5V/2.5A) charge mobile devices directly. The controller allows parallel linking of up to 12 units for megawatt-scale storage, while aluminum housing and forced cooling fans prevent overheating. Critical protections include over-discharge, short-circuit, and reverse polarity safeguards. Ideal for commercial farms or off-grid cabins, it includes a 2-year warrant.
