PowerFlow

E.R.S. Pro

A key accessory for solar PV or wind generators, PowerFlow’s Energy Recovery System (E.R.S.) is a true solar water controller designed from the ground up. By accurately controlling electrical heating loads, such as immersion water heaters or wall mounted space heaters, E.R.S. is able to smoothly divert additional solar energy to be stored as heat.

It does this by cleverly controlling your existing heating device meaning no other specialist heating equipment is required. E.R.S. uses F-Point technology, the fastest measurement method in the industry, taking readings every 200ms and is designed to work seamlessly with the PowerFlow Sundial batteries.
