Product Description

The Voltronic Axpert Ultra 11K 11000W 48V MPPT Off-Grid Inverter is the highest power version of the Ultra family, designed for large and demanding off-grid installations. It integrates an 11 kW pure sine wave inverter, battery charger, and two independent MPPTs (90–450 V) that support up to 12 kW PV (2×6 kW). Includes Wi-Fi for monitoring and OTA updates, 2.8” color touchscreen, internal current sensor for self-consumption with export limitation, and dual AC outputs to prioritize critical loads. Its architecture allows parallel operation of up to 6 units to increase power or create three-phase systems.

Main Features

Nominal power: 11,000 VA / 11,000 W; pure sine wave output 230 VAC.
Dual MPPT 90–450 V, Voc 500 V, up to 12 kW PV and 150 A solar charging.
PV inputs: 2×27 A (max. 40 A); optimal for long strings and different orientations.
Fast transfer 10/20 ms; start-up peak of 22 kVA.
Parallelization up to 6 units; load management via dual AC outputs.
Connectivity: USB, RS232, RS485, Wi-Fi, and dry contact; reserved port for BMS (RS485/CAN/RS232).

Advantages or Benefits

Superior capacity for large homes, workshops, agricultural operations, and SMEs with high demand.
Maximized PV production with two high-voltage MPPTs and up to 12 kW solar array.
Controlled self-consumption thanks to the integrated CT and load prioritization.
Scalability with parallel operation (up to 6) and the possibility of multiphase systems.
Reliable operation with fast switching, pure sine wave, and comprehensive protections.

Purpose or Applications

Recommended for large off-grid residences, micro-industries, farms, rural hotels, telecom, and businesses seeking stable 230 VAC from 48 V, with high solar contribution and intelligent load management.
