Especially in the case of a clouded sky, when light intensity is changing continuously, an ultra-fast MPPT controller will improve energy harvest by up to 30 % compared to the PWM charge controller and by up to 10 % compared to slower MPPT controllers.
If partial shading occurs, two or more maximum power (MPP) 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 SmartSolar algorithm will always maximize energy harvest by locking to the optimum MPP.
No cooling fan. Maximum efficiency exceeds 99 %.
Flexible charge algorithm
Fully programmable charge algorithm, and eight pre-programmed algorithms, selectable with a rotary switch (see manual for details).
Over-temperature protection and power derating when the temperature is high. PV short circuit and PV reverse polarity protection. PV reverse current protection.
The wireless solution to set up, monitor, update and synchronise SmartSolar Charge Controllers.
A Smart Battery Sense, a BMV-712 Smart Battery Monitor or a SmartShunt can be used to communicate battery voltage and temperature (and current, in case of a BMV 712 or a SmartShunt) to one or more SmartSolar Charge Controllers.
For a wired data connection to a Color Control GX, other GX products, PC or other devices.
Up to 25 units can be synchronized with VE.Can, and up to 10 units with Bluetooth.
Will initiate charging even if the battery has been discharged to zero volts. Will reconnect to a fully discharged Li-ion battery with an integrated disconnect function.
Up to 25 units can be synchronised with VE.Can.
To connect for example to a VE.BUS BMS.
Can be programmed to trip on an alarm or other events.
Simply remove the rubber seal that protects the plug on the front of the controller, and plug in the display.
