Off Grid Solar Inverter 48V 8kW Zero Transfer MPPT IP52 | Conversol

The Conversol 8kW IP52 is a 48V pure sine wave off-grid inverter charger for loads that cannot afford to drop out. If the mains fails or goes out of tolerance, it moves to battery power with zero transfer time. Computers, servers, routers and CCTV carry on without a restart.

48V off grid solar inverter features

• Transfer time: 0 ms changeover from mains to battery mode
• Output: 8000VA/8000W of 230VAC pure sine wave power from a 48V battery bank
• Solar input: up to 12,000W of PV across two inputs (30A each, 45A combined), with a 60 to 450VDC MPPT range and 500VDC maximum open circuit voltage
• Charging: up to 120A from solar and up to 120A from the grid or a generator
• Dual AC outputs: the second output can run on a schedule or switch by battery voltage, SOC or discharge time, so non-essential loads drop off first
• Parallel operation: up to 12 units, with central monitoring and an optional remote panel

Monitoring and efficiency

Set-up happens on a touch-sensitive LCD panel. Integrated Wi-Fi links to an app showing daily, monthly and yearly data. Efficiency reaches 94% in line mode, 98% in ECO mode and 93% on battery, and no-load current is kept below 1A to cut standing losses. Live Firmware Update (LFU) lets the software be updated without interrupting the AC output. Communication ports include USB, RS232, RS485, Wi-Fi and a dry contact.

Applications

Off-grid homes, cabins and holiday lets running on solar and battery storage. Backup for home offices, IT equipment, servers and network cabinets. Small commercial premises where computers, tills or CCTV must stay online, along with farms, workshops and outbuildings lacking a reliable grid supply. It also fits solar and generator hybrid systems on a 48V bank.

Installation and the IP52 rating

IP52 means dust protected and resistant to water dripping vertically with the unit tilted up to 15 degrees. It is not waterproof. Fit it indoors or in a dry, sheltered spot such as a garage, plant room or weatherproof outbuilding, away from rain, spray and condensation. Operating temperature is -10°C to 50°C at 5% to 95% relative humidity (non-condensing), and the ventilation clearances must stay free.

The inverter must be installed by a qualified electrician or MCS certified solar installer in line with BS 7671. Confirm battery and BMS compatibility, charge voltages and current limits with your battery supplier before commissioning. PV open circuit voltage must never exceed 500VDC at the coldest expected temperature. This is an off-grid unit and does not export to the grid.
