JUST. SO. PRO
E.R.S PRO sets new standards for solar immersion control.
It's dual 3kW programmable outputs 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+
The most powerful
solar immersion controller
Plug and play connectors
The E.R.S PRO features high quality German engineered connectors ensuring a high quality secure connection. This results in a quick and efficient, trouble free, installation.
F-POINT technology® Advanced Power Control
• Reaction time of <200ms, eliminating unwanted grid import during operation
• Automated management of surplus solar energy to run heating device
• Intelligent self-learning algorithm means automated setup
• Output levels from 5% to 100% of load
• Efficient control results in extremely low loss, 98% efficiency
• Emissions of EMI, EMC, Flicker and Harmonic distortion surpass industry standards
E.R.S PRO has a 2 year warranty as standard, backed by PowerFlow. This can be extended to 5 years for free by registering your product on the warranty page. If you have an issue we will get you up and running
Smart and manual boost functions
The E.R.S PRO incorporates smart boost which intelligently applies the boost function when generation is low for a period of time. Lack of export power will automatically trigger the boost function for the set period. The function can be turned on or off in the settings menu and is particularly useful in all electric single tariff households.
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 recovery function, supplying mains power directly to electrical load. This 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 testing of the electrical load circuit without risking damage to the device.
Metal case for cooling and dust / moisture resistance
The E.R.S PRO is sealed against the ingress of dust and moisture to protect the internal electronics, to IP44. The result: no dust ingress to overheat internal components and no moisture ingress to corrode the electronics. This increases reliability which leads to longer component life.
The backlit LCD display shows live information about the system status. The display features; auto time out - 5 minutes; live exported power; live imported power; live output power; operation status and total kWh savings.
External override timer and smart relay
The E.R.S PRO has an auxiliary connection which can be used with a standard external timer. The timer will override the E.R.S function during the timed period. The function can be turned on or off in the settings menu. This feature is particularly useful in all electric households with a night rate electricity tariff or in installations containing heat pumps.
Fully compatible with third party battery systems
F-POINT technology® is PowerFlow's patented power control measurement system. With reactions to changes in export levels of five times per second E.R.S is in a class of its own. This enables the measurement system to be adjusted according to any third party battery systems meaning priority can be set for either device.
& Full Control
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.
Advanced F-POINT Technology®
F-POINT technology® ensures energy is always supplied from the renewable source, eliminating unwanted import. This is essential in commercial applications where large amounts of energy is being transferred.
The Swiss Army Knife Of Solar Immersion Controllers
E.R.S PRO can do it all. When it comes to designing solar immersion systems. PowerFlow's technologies give almost limitless flexibility to the installer.
From its dual assignable outputs with override control, to its programmable relay, capable of controlling third party (inductive) loads, E.R.S PRO is the most versatile solar diverter on the market.
The LCD display gives live accurate information on the buildings energy demand and the easy to use menu gives flexible setup options for both installer and user.
Designed for large domestic and commercial PV or wind generation systems, both single and three phase, E.R.S PRO can adjust its output from 150W 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 equipment.
