Silent Power Cabinets

Fully wired off-grid control cabinet. 16kW Single Phase 230V. 48V Lithium & Lead Acid Batteries Compatible.

A bespoke system that meets the requirements of off-grid electrification and supports power independence from the national grid. You can contact our team to discuss the development of your own power station, a unique service in the UK that is offered exclusively by Voltacon.

Skip the complications and head straight for the comfort and freedom of a complete energy system. This multifunctional energy system brings together a powerful sine wave inverter, a sophisticated battery charger, a high-speed AC transfer switch and AC distribution in a single lightweight and compact enclosure, which cuts down on the time required to install and eliminates pesky technical procedures that could crop up for the novice installer. The result is a seamless installation process with a control cabinet that works hard -- though you'd never be able to guess!

Every Silent Power Off-Grid Photovoltaic Control Cabinet is designed with a state-of-the-art battery monitoring system with added Bluetooth connectivity. Access temperature and energy status update and avoid premature failures via any Android-based mobile phone.

To get started, simply connect the solar panel and battery cables to the protected power terminals of the cabinet. The Silent Power Off-Grid Photovoltaic Control Cabinet is a complete system that focuses on energy but keeps the user at the center of its design. 

Voltacon develops plug'n'play off grid control cabinets that are made in the UK for continuous 230VAC power supply. The main power conversion system is our Conversol inverter/charger with active output power 16000W, the MPPT 150A solar charger, and the battery monitor from Victron (BMV-712). In this version, we have added the parallel function with two 8kW Max inverters. 

The cabinet is fully wired with 70mm2 battery cables, double insulated solar cables with fused terminals and DC battery distribution system using 1000A bus bars (Lynx Distributor from Victron with 200A fuses).


The Solar-Assistant with Orange PI 3 LTS is included and programmed ready to monitor your inverter performance over the internet. No annual fees are required.
