WATTrouter product line

How to choose the best model for me:
  1. Check the value of main fusing element (fuse or circuit breaker) in your house. Select possible models according to the first row of the table below. The model WATTrouter M MAX is suitable ONLY for main fusing element higher than (or equal to) 3x40A!
  2. Check the peak power (kWp) of your PV or wind plant and number of phase wires where this plant is connected to (typically you have single phase or three phase inverter). Select possible models according to the fourth row of the table below.
  3. According to required level of user comfort choose from M series or ECO series. The M series can be connected to Internet, offer advanced control techniques with programmable time schedules, have more quiet fan and other advantages.

Notes:

  1. It is possible to connect one standalone regulator to each phase wire to get up to 18 outputs.
  2. The current sensing module can be connected to external current transformers to increase current load and measurement range. For these purposes we recommend to choose WATTrouter M SSR or WATTrouter ECO.
  3. The WATTconfig application for Linux is provided without any user support.
  4. PWM mode can be used even for suitable battery chargers.
  5. The function must be purchased as extra software feature.
  6. Proportional control of immersion heaters and other heating elements ALWAYS needs an external solid state relay (SSR)!
  7. Requires the SC-Gateway and SC-Router wireless cards.
