PMW Solar Charge Controller offers efficient energy management for photovoltaic storage, with its AS series PWM charge controller (10A-50A). Key advantages include PWM intelligent charging, multi-battery compatibility, and precise power control. Utilizing PWM technology (98%+ efficiency), it supports 12-48VDC input, adapts to lead-acid/lithium batteries, and dynamically optimizes solar panel output. Parameters: 10-50A current, 10-150V input, floating/equalizing/circuit charging (10-20% power increase). Features: reverse connection, overload, short circuit, over-temperature protection, load control, IP65 rating, ideal for off-grid, RVs, and marine applications. Intelligent battery management extends battery life by 30%+.
