Snaptec Australia Pty Ltd has added the SBS-MP-75-50 maximum power point tracking solar charge controller to their expanding range of innovative solar power conversion products.
A new and unique solar panel charge controller unit, the SBS-MP-75-50 is rugged and compact in design, and can handle open circuit voltages of up to 75V and supply a charge current of up 50A, allowing the use of these solar charge convertors with a wider range of solar panels available in the market.
Several advanced features set the SBS-MP-75-50 apart from other products on the market.
Charge current up to 50 A and PV voltage up to 75 V
The SBS-MP-75-50 charge controller is able to charge a lower nominal voltage battery from a higher nominal voltage PV array, automatically adjusting to a 12V or 24V nominal battery voltage.
Ultra-fast Maximum Power Point Tracking (MPPT)
During cloudy conditions, when light intensity is changing continuously, an ultra-fast MPPT controller will improve energy harvest by up to 30% compared to PWM charge controllers, and by up to 10% compared to slower MPPT controllers.
Advanced Maximum Power Point Detection in partial shading
During partial shading, two or more maximum power points may be present on the power voltage curve. Conventional MPPTs tend to lock to a local MPP, which may not be the optimum choice. The SBS-MP-75-50 solar algorithm will always maximise energy harvest by locking to the optimum MPP.
Outstanding conversion efficiency
Maximum efficiency exceeds 98% with full output current up to 40°C; no cooling fan is required.
Flexible charge algorithm
Eight pre-programmed algorithms, selectable with a rotary switch.
Extensive electronic protection
Over-temperature protection and power derating when temperature is high, PV short circuit and PV reverse polarity protection, and PV reverse current protection are some of the benefits.
This SBS-MP-75-50 is part of a range of solar products available from Snaptec that include MPPT charge controllers, solar grid inverters to optimise energy storage, solar panels and solar batteries.
