The Next Generation of Solar Immersion Controller for 2018

E.R.S PRO sets new standards for solar immersion control
Dual programmable outputs can be set to run a multitude of heating devices all at the same time.
In addition these two output can be combined together to run a single 6kW heating device, another industry first.


Class Leading Control

Proactive not Reactive

E.R.S PRO intelligently considers how much power is being generated and how big each load is. 
Each Output can be assigned priority as required dictating how much energy is then diverted to each load. 

Combined with the powerful F-POINT technology®  advanced power control, 
this ensures that energy is always supplied from the renewable source only and unwanted import doesn't occur. 

This is essential in applications where a large amount of energy transfer is being performed.

Dual Outputs

Clever Thinking

The ERS 6 Blue Edition contains 2 x 3kW outputs that can be configured for almost any heating requirement. 

In parallel mode each output can be connected to independent heating loads up to 3kW each and assigned a priority, 
or they can be combined together to run a single 6kW heating load. 

This is all achieve through a single high quality plug and play power connector. 

Total Control 

Built in bypass

The E.R.S PRO incorporates a fully independent manual isolation and by-pass switch 
Simply flick the switch to turn off the unit or by-pass the energy recovery function

The feature can be used if the electrical device is required to be turned on manually or E.R.S is not required for a period of time 
It can also be used for regulatory safety testing of the heating device without risking damage to your ERS device 

Commercial scale E.R.S with 3 phase 

Up to 18kW of 3 phase solar recovery with E.R.S PRO

Designed for solar PV or wind generation systems of 10kW and above, typically found in commercial applications, 
ERS 6 Blue Edition can control generated power from as little as a staggering 200 Watts all the way to 18,000 Watts per phase.

ERS 6 Blue Edition is an ideal partner in combination with biomass or heat pump systems. 
The ERS 6 Blue Edition can be used to divert exported energy into the accumulator tank helping to reduce wood or electricity cost. 

During operation in a 3 phase installation, ERS also helps to correct any phase imbalance, 
this results in increased efficiency of any 3 phase equipment that maybe running at the same time.

Storing solar energy as hot water is currently the cost effective way to use your surplus solar energy
 Built to industry leading standards, including a host of new features and increased performance, 
ERS 4 Silver Edition has a class leading finish, is flexible, efficient and user friendly. 

Fully automated. Completely in control

Live LCD display gives accurate information on your homes energy demand and system status.

Accurately tracks surplus solar power, diverting excess into existing heating loads such as immersion or space heaters

Eliminates unwanted import during operation due to fast reacting F-POINT technology

Powerful electronics provide 4kW of output to any heating device 



Useful Features 

Easy to use menu gives flexible setup options for both installer and user

Three position
 main power switch incorporating safety test isolation, ERS operation and manual bypass positions.



Flexible Design

The ERS 4 Silver Edition will run almost any heating device 

This means you can't run your fridge or freezer but you can run the following: 

Immersion heaters
Oil filled towel rails for bathroom heating 
Storage heaters or electric bar heaters for space heating 
Electric underfloor heating

External devices can also be controlled using the smart relay feature as well 
as external timers for use with economy 7 electricity tariffs.
