Product Description

The Voltronic Axpert Ultra 8K 8000W 48V MPPT Isolated Inverter is designed for off-grid installations that require high power, flexibility, and advanced control. It combines an 8000 W pure sine wave inverter, battery charger, and two independent MPPT solar controllers with a wide range of 90–450 V, allowing for high-voltage strings, fewer cable sections, and a more efficient PV design. It features Wi-Fi for monitoring and OTA updates, a 2.8” color display with slide operation, dual AC outputs for intelligent load management, and an integrated current sensor that enables self-consumption mode with export limitation.

Main Features

Rated power: 8000 VA / 8000 W with pure sine wave at 230 VAC.
Dual MPPT 90–450 V, max PV Voc 500 V, up to 10 kW PV (2×5 kW) and 150 A solar charging.
Independent PV inputs: 2×27 A (max. 40 A) to configure two arrays or orientations.
Fast transfer: 10 ms (PC) / 20 ms (appliances). Peak: 16 kVA.
Parallelizable up to 6 units to increase power or phases.
Communications: USB, RS232, RS485, Wi-Fi, dry contact, and reserved port for BMS (RS485/CAN/RS232).

Advantages or Benefits

Higher production thanks to high-voltage MPPT and two PV inputs for east/west or expansions.
Off-grid self-consumption with integrated current sensor that prioritizes loads and limits exports.
Continuity with fast switching and pure sine wave that protects sensitive electronics.
True scalability: parallelization (up to 6) and up to 10 kW PV supported.
Professional management with Wi-Fi, color LCD, and internal logs for diagnostics.

Purpose or Applications

Homes and isolated properties with medium-high consumption, light agro-industry, workshops, telecommunications, radio links, and businesses in areas without grid or with generator. Ideal when a modular, expandable system with controlled self-consumption is required.
