Inverter.

A pure inverter only produces 230 V from the battery. An inverter-charger also charges from shore power or a generator and switches automatically between the sources. If you already have a separate charger or only use 230 V appliances occasionally, a pure inverter such as the Studer AJ series or the Mastervolt Mass Sine is often sufficient.

Add up the power of all appliances running at the same time and allow for the starting current of motors and compressors, which can briefly be several times higher. The Studer AJ series ranges from 200 VA continuous (AJ 275) to 2000 VA (AJ 2100 and AJ 2400). The DCW series delivers 2000 or 3000 W.

Sine wave inverters produce a clean AC voltage like a mains socket and therefore reliably supply sensitive electronics, laptop chargers and appliances with motors. Simple square wave or modified wave inverters can disturb or damage such devices. The inverters in this category, i.e. Studer AJ, Mastervolt Mass Sine and the DCW series, are sine wave inverters.

Yes, depending on the model. The Studer AJ 275 is designed for 12 V; the larger AJ models come for 12 V and 24 V, for example AJ 1000 and AJ 1300. The DCW series is available for 12 V and 24 V, while the Mass Sine versions sold by philippi are for 24 V.

With the Studer models AJ 1000/1300 and AJ 2100/2400, yes, using the FB-AJ remote control. It comes with a 5 m connecting cable and shows the operating status visually and acoustically. The AJ 275 and AJ 500/600 cannot be remote-controlled. The DCW series is displayed and adjusted via the P-Bus on the PSM3 and PSL monitors.
