The system
Solar and storage at the centre of everyday power.
This customer’s property operates independently of the National Grid. The installation combines a Victron MultiPlus-II 10 kVA inverter/charger with a Victron MPPT RS450 solar charge controller.
Two independent MPPT trackers connect the two solar arrays. Storage is provided by two Dyness 10.24 kWh lithium battery modules, giving 20.48 kWh of nominal capacity.
The installation also includes local system monitoring and clearly labelled isolation and bypass switching, bringing the main controls together in one equipment area.
Planning beyond the first installation
Room for the system to grow.
The system was designed with provision for a second inverter when the customer is ready to expand. Future requirements were considered in the initial equipment arrangement.
For an off-grid property, electrical demand, solar availability and storage capacity need to be considered together. The aim is a system suited to how the site is used, with clear operating arrangements and a practical route for future development.
The experience behind the design
Specialist Victron knowledge, applied on site.
SES founder Thomas Howe has extensive experience with Victron-based power systems and has trained other installers on their use. His work spans electrical engineering, renewable generation, storage and system integration.
This project brings that experience to an off-grid installation, combining the inverter, solar charging, batteries and operating controls as one system.
