PowerAssist - Extended use of AC input current
This feature is an extension of PowerControl by allowing the Multi RS to supplement the capacity of the available AC input power source. Where peak power is often required only for a limited time period, the Multi RS will make sure that insufficient AC input power is immediately compensated for by power from the battery. When the AC load reduces, the available AC input power is used to recharge the battery. The Multi RS can provide throughput of up to 50 A to the loads. The AC input relays are limited to 50 A (Multi RS - 2 tracker), and the inverter can contribute up to 25 A continuous at best conditions (when it gets hotter this figure will be reduced). This power comes from either the battery and/or the DC PV (the DC PV power also has to go through the inverter before it reaches the AC loads).
The Multi RS can provide throughput of up to 50A to the loads. The AC input relays are limited to 50A, and the inverter can contribute up to 25A continuous at best conditions (when it gets hotter this figure will be reduced). The additional AC power is supplied from the battery.
Warning
The AC output must be protected from over current. A circuit breaker rated at 50A or less is required at the AC-output terminals.
