Charge Controllers
1. Streetlight Charge Controllers
Our streetlight charge controllers can be automatically set to the preferrable times intervals of being on/off or they use a sensor to switch on/off by detecting the charge from the solar panels.
KEMA Streetlight Charge Controllers
The KEMA streetlight charge controllers 12V/24VDC 10A,20A have a full aluminium shell with IP68 waterproof, quakeproof, anticorrosion, and automatic recognition of day and night. They also have a reverse connection, overload, short circuit and over voltage protection.
2. PWM Solar Charge controllers
Our PWM Solar Charge controllers are available from as low as 5Amps to 60Amps with rated DC voltage in 12/24/48 volt
PWM-KEMA Solar Charge Controllers
The KEMA solar charge controllers 12/24V 10/20/30A have an LED display with LED indicators for charging, load, fault, and protection status for over charge, over discharge, overload, short circuit, and reverse polarity. They also have USB charging ports and an RJ45 option for connecting to the computer.
3. MPPT Solar Charge Controllers
Our MPPT Solar Charge controllers are available from as low as 20Amps to 80Amps with rated DC voltage in 12/24/36/48 volts.
MPPT-KEMA Solar Charge Controllers
The MPPT KEMA solar charge controllers 12/24/48VDC 20-80A have a maximum PV input of 150VDC with 98% conversion efficiency. These charge controllers have the capacity to control PV voltage, limit maximum charge current, and protect batteries from over charge or over discharge. They also have an RS485 PC monitoring and Wi-Fi APP monitoring Option.
MPPT-Victron Solar Charge Controllers
The MPPT-Victron Solar Charge Controllers have smart built-in Bluetooth technology for wireless solution to set-up, monitor, update and synchronise Smart Solar Charge Controllers. They also have VE.Direct for a wired data connection to a Color Control GX, other GX products, PC or other devices.Especially in case of a clouded sky, when light intensity is changing continuously, an ultra-fast MPPT controllers will improve energy harvest by up to 30% compared to PWM charge controllers and by up to 10% compared to slower MPPT controllers. If partial shading occurs, 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 MPP. The innovative BlueSolar algorithm will always maximize energy harvest by locking to the optimum MPP.
These controllers do not have cooling fans because their maximum efficiency exceeds 98% and full output current up to 40°C. They also have extensive electronic protection for over-temperature and power derating when temperature is high, PV short circuit and PV reverse polarity, and PV reverse current protection.
