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.

Electronic protection functions

All the sizes of the Steca Solsum charge controllers guarantee all the fundamental protection functions for this type of device, such as:

Overcharge protection
Deep discharge protection
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

Steca Solsum 0606, 0808, 1010 solar charge controllers

The Steca Solsum continues the huge success of one of the most used SHS controllers. With a power range of up to 10 A at automatically recognized 12 V or 24 V it fits to a system sizes of maximum 240 W.

Full circuit board protection with LED display for simple recognition of battery status. Various connections make it possible to connect easily to solar panels, battery and load. The Steca Solsum F works on PWM as a low loss series controller.

* 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
