Fronus Xeon Advance 1.4 kVA Off-Grid Inverter

Note: 1400 VA on a 12 V battery bank, with a built-in 50 A MPPT solar charge controller, a smart LCD, overload and output short-circuit protection, and lithium-ion battery compatibility. AC output is reported at 220 to 240 V. No Fronus datasheet exists for this model. Everything here comes from the surviving Xeon owner's manual and from Pakistani retailer listings, so the page carries only what those sources actually state and leaves every unverified field empty rather than guessing. The output waveform is the open question: the model-specific retail documentation describes a modified sine wave, while other listings claim pure sine. A modified sine wave runs heating and simple motors, but it is hard on inverter-driven fridges, some fans and sensitive electronics, so settle this before buying. Retailer listings also report 120 to 150 Ah of recommended battery, 0 to 40 °C operation, 360 x 150 x 300 mm and 7.5 kg, but none of that is confirmed by Fronus, so it is not recorded in the fields above. The PV array power, MPPT voltage window and open-circuit ceiling are not published anywhere reliable. Ask the dealer for the nameplate photo before you size an array or a battery bank against it. This is a legacy model: the Fronus range now sells under the Platinum and Infineon Reborn lines, which carry full datasheets.
