Versions and Options

All systems are 3 phase capable out of the box.
You can switch between ELC mode and IGC mode with a menu setting.
Intermediate power ratings/channels are of course possible. Ask for a bespoke quote.

If your dumploads require currents above 12A (more than 3kW at 220V) per dumpload, we can adapt the  design to allow for up to 50 A per channel. Please tell us your requirements.

Above 200kW

The current controller board design allows for 45 channels at 40 A, switching 1800 A or 450 kW in total. More is possible by combining 2 or more controller boards.

However consider regulating the power generation by also regulating the water flow. This saves the cost for providing and switching dumploads, and it saves water, especially if you have a water reservoir.
The microcontroller board provides water regulation feature as standard.

it would enable you to watch all parameters realtime. This feature is still in beta phase. Real time graphs not available at the moment.
The main purpose of the network feature is that you receive a warning if critical parameters go out of range, for example via email. (without you having to look at the parameters all the time)

Redundant power supply

Second 5V powver supply for redundancy.
Primary voltage110/220VAC.
If you have a12/24V DC battery power supply on site, this second power supply can also be powered by 12/24V.

DC monitoring

 Isolated, potential-free DC monitoring input.

This is a special galvanically isolated analog input to monitor the voltage of a battery, e.g. 12V lead battery. For example useful for systems which have a battery as power supply backup.

Additional analog inputs
 32 additional A/D inputs to monitor all kinds of things like bearing temperatures, voltages, currents etc.

If your system has sensors in other components (e.g. temperature sensors on the turbine bearings or sensors from water valves, water intakes, water tanks, pressure sensors,  etc.), the information from these sensors can be put to use.

Sensors not included.
inputs not isolated, connected to DC ground / AC neutral
