steca Pr Range Regulators
The Steca PR charge controllers were launched in the year 2004 as the fifth generation of charge controller technology (up to 900 Wp). This high-class, state-of-the-art product upgrades the Steca Solarix series.
A customer-designed LCD shows the accurate state of charge (SOC) in percent as fuel gauge symbol to show the battery state of charge (SOC). The heart of the controller is the integrated circuit called ATONIC®II, which contains the improved regulation software based on a self learning algorithm.

Important Note: NO replacement or refunds will be given for regulators which have had their low voltage disconnect blown. Do NOT excede the stated amperage of the regulator as this is not covered by the warranty. Follow the instructions which are supplied with the regulator, DO NOT LEAVE THE REGULATOR CONNECTED TO ACTIVE SOLAR PVs WHILE CHANGING THE BATTERY PACK. THIS WILL VOID THE WARRANTY AND NO REPLACEMENT CAN BE MADE.Do Not connect any inverter directly to the outlet of these regulators, even if the stated amperage falls below that of the regulator. Momentary surges will destroy the regulator.
