Automated EV Charging

Most drivers travel only 30–40 miles a day, roughly 10–15% of a typical EV’s range. A 200-mile trip might come up once a week. That means your car doesn’t need a fast, full charge every night. Instead, it can charge slowly through the week using only the excess solar your home produces.

Smart chargers are tailored for fully off-grid as well as grid-tied battery coupled solar systems. Simply plug the receiver into UART or Modbus port into battery BMS and start charging with some of the preset algorithms.

With grid-tied battery the goal is to not sell energy back to the grid at a steep discount, while using power when it’s available saves your battery from unnecessary wear.

You choose how your EV charges by setting a priority in the mobile app or on the charger itself:

High priority charges at full power, no matter what.
Medium priority charges at full power until your home batteries drop to a level you set (for example, 40%), then switches to excess solar only.
Low priority charges using excess solar only.

Even when your EV shows 200 miles of range, the battery often has 20–40 kWh of room left. Filling that space with solar that would otherwise go to waste is one of the most affordable ways to reduce how much home battery storage you need.

Compatibility: Using Modbus communication, our system can read data from almost any lithium battery bank’s battery management system. It can share that data over your home Wi-Fi or wirelessly with a network of load controllers.
