Go Off Grid in No Time: Fully Wired and Tested Solar Inverter Cabinet

Overview

This cabinet is designed and assembled by professional solar engineers in the UK. We have selected the correct protection devices, cable sizes, and automation so the system can start generating electricity as soon as you connect the batteries and solar panels. No extra wiring work is required from the installer.

Built for true off grid electrification, the cabinet also includes backup power connections for a diesel generator. Although this is an off grid system, many homeowners with a grid connection choose this solution to increase energy independence. The grid can be used as a backup source and to charge batteries overnight on lower cost tariffs (subject to your electricity plan).

Key Features

• 22kW single phase off grid output (two 11kW MAX II inverters in parallel)
• Dual parallel Conversol MAX inverter chargers for added redundancy
• Plug and play cabinet design for faster commissioning
• Grid and generator backup compatible
• High speed AC transfer and integrated distribution
• UK wired and tested before dispatch
• Charge from the grid overnight on low cost tariffs
• Built in AC charger timers within the inverter settings

Remote Monitoring and Battery Intelligence

A Raspberry Pi 5 is pre installed and configured to monitor both inverters and the battery bank (Pylontech US5000C recommended). The system supports remote monitoring and control through the Solar Assistant platform via your local Ethernet network. Wi Fi connectivity is also available.
