Today we released firmware version v1.11 for all RS products, being the Multi RS, Inverter RS as well as both MPPT RS models.

The most important changes all concern the Multi RS, and are:

• Add support for using a generator as AC source: the inverter has an increased tolerance for irregularities on the ac input like fast frequency changes or voltage changes. For robust generator control enable 'moderate generator load changes' and switch off the 'UPS function'. This includes a new setting, called 'moderate generator load changes'. Enabling this lets the inverter absorb sudden load changes and slowly transfer them to the generator. This prevents speed variations in the generator.
• Add 'UPS function', this realizes a faster transfer to inverter mode when the mains stops. This function is enabled by default.
• Reduce charge current at higher battery voltages and/or lower AC input voltages. At 230V, the maximum charge current at 57.6V is now approximately 88A unless derated due to ambient/internal temperature. The maximum achievable charge current was higher, approximately 95A under the same conditions.
