MPPT Solar Charge Controller
This MPPT Solar Charge Controller is used in solar off-grid system (independent system), especially suitable for street lamp control system, which automatically adjusts charging and discharging.
This MPPT Solar Charge Controller is used in solar off-grid system (independent system), especially suitable for street lamp control system, which automatically adjusts charging and discharging. The controller has an advanced tracking algorithm to obtain the maximum power of the solar module to charge the battery. At the same time, its low voltage disconnect (LVD) function can prevent the battery from being over-discharged and causing damage. The controller's battery charging process is optimized to extend battery life and improve system performance. At the same time, the controller has multiple self-diagnosis and electronic protection functions to avoid user damage caused by misoperation or system failure.
Untra-fast Maximum Power Point Tracking (MPPT solar charge controller)
Advanced Maximum Power Point Detection in case of partial shading conditions
If partial shading occurs, two or more maximum power points may be present on the power-voltage curve. Conventional MPPT tends to lock to a local MPPT, which may not be the optimum MPPT. The innovative leyu algorithm will always maximize energy harvest by locking to the optimum MPPT.
Outstanding conversion efﬁciency
Our MPPT 100-30 does not need cooling fan. Maximum efficiency exceeds 98%. Full output current up to 40°C (104°F).
Flexible charge algorithm
Fully programmable charge algorithmand eight switch.
Extensive electronic protection
Over-temperature protection and power derating when temperature is high. PV short circuit and PV reverse polarity protection. PV reverse current protection.
