The most powerful solar immersion controller available


E.R.S PRO sets new standards for solar immersion control. It's dual 3kW programmable outputs can be can be configured up to 2 x 4kWs if required. These can be set to run a multitude of heating loads independently, or be combined together, with the smart relay for the control of more devices. In addition commercial Three phase systems can be configured up to 27kW+


F-POINT technology® is PowerFlows patented power control measurement system. With reactions to changes in export levels of five times per second. This enables the measurement system to be adjusted according to any third party battery or other storage devices enabling the user to set priority. The installer has almost limitless design flexibility making the E.R.S PRO the most versatile solar diverter available.


Designed for large domestic and commercial PV or wind generation systems, E.R.S PRO can adjust its output from 150W single phase up to 27,000W three phase. E.R.S also helps to correct any phase imbalance during operation, resulting in an increase in efficiency of power hungry three phase equipment.

E.R.S PRO is an ideal partner in combination with biomass or heat pump systems and can be used to divert exported energy into large thermal stores and buffer cylinders helping to reduce chip or electricity cost.


Third party battery compatibility:

With fast reactions to changes in export levels the measurement system can be adjusted to run in conjunction with third party energy storage systems. This lets the user set priority of devices.


Fan-less cooling:

The E.R.S PRO has a custom made aluminium enclosure. The result: Silent running, increased reliability and system efficiency.


Crystal clear display:

The LCD display gives live accurate information on the buildings energy demand and the easy to use menu gives flexible set-up options for both installer and user.


Boost feature:

The manual boost button, situated on the front of the E.R.S and enables the user to override the E.R.S mode for a timed period. This will allow a boost of hot water or heating. The timed period is adjustable through the menu from 10 - 120 minutes.


Smart boost function:

The E.R.S PRO incorporates smart boost which intelligently applies the boost function when generation is low for a period of time.
