The Conversol Max 11kW is a single-phase off-grid solar inverter charger delivering 11kW continuous pure sine wave AC output and 11kW PV input via dual independent MPPT. It runs on a 48V DC battery bank and works with lead-acid, GEL, lithium-ion and LiFePO4 batteries, with BMS communication ports already fitted for lithium setups.

11kW solar inverter charger features

• AC output, 11kW continuous pure sine wave
• PV input, 11kW via dual independent MPPT
• Battery voltage, 48V DC, compatible with lead-acid (AGM, GEL, flooded, forklift), lithium-ion and LiFePO4
• Battery-independent operation, runs loads direct from solar with 8 to 10 panels in series minimum
• Monitoring, built-in Wi-Fi for Android and iOS, plus RGB status indicator and USB On-the-Go
• Parallel operation, up to 6 units, giving 66kW single-phase or three-phase configuration

Applications

Suited to large off-grid residential properties, farms, workshops and light commercial or industrial sites where continuous AC demand reaches or exceeds 11kW. It handles agricultural loads such as water pumps, air compressors and refrigeration, and can support off-grid EV charging, heat pumps and air conditioning at 230V.

Parallel and redundancy

Parallel hardware and communication ports come pre-installed, so units can be linked to scale output without extra interface hardware. If one unit in a parallel array fails, the rest keep supplying power, so the system has built-in redundancy.

Battery-independent mode

The inverter can feed AC loads directly from the solar array without a battery connected, as long as the PV string voltage is high enough. Voltacon recommends a minimum of 8 to 10 panels wired in series for this mode.

Installation notes

This is an 11kW system and must be installed by a qualified electrician or solar installer, with correct cable sizing, busbar ratings, fusing, DC and AC isolators, surge protection and earthing. Battery systems must comply with BS EN 62619 and local building regulations.
