3000 W PV inverter for off-grid stand-alone operation

EFFEKTA

Power Supplies

NEU / NEW

The EFFEKTA® VX-Series inverter is an off-grid Potovoltaik inverter, which obtains its power from three sources of electricity: photovoltaic modules, rechargeable batteries or an AC power source. It can be both a source of AC power generator and the utility grid. At insufficient power supply from the PV modules the unit completes the missing power requirements automatically with the help of batteries. At night or in complete failure of PV modules, the inverter will automatically switch to the AC power source. Above: All the important data of your PV system can be

monitored via the extensive display.

Supplying of the consumer over the batteries is part of the functional principle of the EFFEKTA VX, e.g. if the minimal solar radiation doesn’t have enough capacity over the PV-modules. The operation is with AGM, Gel, NiCd, closed lead acid battery (OPzS, OPzV …) possible. The batteries will be charged over the integrated 3-stepped battery charger in the VX. (schema right). EFFEKTA® advises the Rolls™ brands batteries of the type 4000 - T12 250 and 5000 - 12 CS 11P for the sys-tem. More types can be requested.
