Steca Solsum F series of charge controllers for off-grid systems

Steca, an important German brand in the production of devices for off-grid systems, has introduced the new series of charge controllers Steca Solsum F 0606, 0808, 1010.

These products have a power range that can reach 240 W thanks to a maximum current of 10 A and a voltage of 12 or 24 V.

This series of devices can easily connect to solar panels, battery and loads. Thanks to the LEDs on the device, it can also always monitor the battery status.

Steca Solsum F 0606, 0808, 1010

The new Steca Solsum F is a device divided into 3 sizes: 0606, 0808, 1010.

They are distinguished by two fundamental features, which are the input current module and the charging current.

In the specific case the currents are:

  • model 0606 equal to 6 A
  • model 0808 equal to 8 A
  • model 1010 equal to 10 A

As for the other technical data, there are no relevant differences between the 3 sizes of products.

  • Reverse polarity protection of module (≤36 V),load and battery
  • Short circuit protection of load and module
  • Overvoltage protection at module input
  • Open circuit protection without battery
  • Reverse current protection at night
  • Overtemperature and overload protection
  • Load disconnection on battery overvoltage

* Solar charge controller is protected against reverse battery polarity together with
polarity protected loads. Reverse battery polarity combined with short circuited or
polarised load could cause damages in load or regulator
* The reverse-polarity protection of the solar module in a 24 V system is only provided
up to an open-circuit module voltage of 36 V.
* Lower value for nominal current, higher value for lowest current
