The intelligent Load output function prevents damage caused by running batteries ‘flat’. You can configure the voltage at which BlueSolar disconnects a load – thereby preventing excessive drain on your batteries. And here’s the clever bit: BlueSolar will attempt a 100% recharge every day. If it can’t – during periods of poor weather – it raises the disconnect voltage, daily, until it achieves success. We call this feature BatteryLife because it maintains health, and extends the life of your battery.

When a solar charge controller is not able to recharge the battery to its full capacity within one day, the result is often that the battery will continually be cycled between a ‘partially charged’ state and the ‘end of discharge’ state. This mode of operation (no regular full recharge) will destroy a lead-acid battery within weeks or months.

The Battery Life algorithm will monitor the state of charge of the battery and, if needed, day by day slightly increase the load disconnect level (i.e. disconnect the load earlier) until the harvested solar energy is sufficient to recharge the battery to nearly the full 100%. From that point onwards the load disconnect level will be modulated so that a nearly 100% recharge is achieved about once every week.
