Dual Sigenergy Full-Time Off-Grid Home with Power for Everyday Living
24kW inverter capacity, 20kW rooftop solar and 54kWh usable battery storage for a fully off-grid family home.
100UP installed this dual Sigenergy off-grid solar system for a residential property in Malmsbury, near Castlemaine in regional Victoria.
The installation combines 42 rooftop solar panels, two 12kW Sigenergy SigenStor inverters and six lithium battery modules, providing substantial solar generation and battery storage for everyday household electricity needs.
Designed for full-time off-grid living, the system provides capacity for household appliances, heating and cooling, and other electrical loads without relying on a mains electricity connection.
Solar Power for Everyday Off-Grid Living
A full-time off-grid home needs enough electricity for more than lighting and basic appliances. Cooking, heating and cooling, hot water and other household equipment can create substantial electrical demand, particularly when several appliances are running together.
For this Malmsbury property, 100UP installed two 12kW Sigenergy inverters, providing a combined 24kW of single-phase inverter capacity.
The dual-inverter configuration gives the household greater capacity to run multiple electrical loads at once, without needing to carefully stagger every appliance.
Battery Storage for Nights and Cloudy Weather
Six Sigenergy battery modules provide a reported 54kWh of usable energy storage.
During daylight hours, solar generation supplies the home’s electricity needs while available excess energy can recharge the batteries. After sunset, the household draws on stored energy.
This is especially important during regional Victorian winters, when shorter days and cloudy weather reduce solar production.
The actual time the batteries can support the home depends on how much electricity is being used, the battery’s state of charge and how much solar energy is available to replenish it.
20kW of Rooftop Solar Generation
The property’s shed roof accommodates 42 solar panels rated at 475W each, giving a combined solar capacity of 19.95kW.
Using the shed roof provides a substantial area for solar generation while keeping the panels separate from the main homestead.
The solar array works alongside the battery bank to cover daytime consumption and restore stored energy for overnight use.
Integrated Sigenergy Energy System
The two SigenStor inverter and battery stacks are installed inside the property’s shed, alongside a Sigen Gateway HomePro SP-F AU.
The integrated equipment manages solar generation, battery charging and electricity supply to the home.
Locating the equipment inside the shed also gives it a protected installation environment, with the gateway and battery systems accessible for inspection and servicing.
Built for a Home That Lives Off-Grid
This Malmsbury installation brings together substantial rooftop generation, dual-inverter capacity and modular battery storage in a single residential off-grid system.
The aim is straightforward: provide enough generation, stored energy and inverter capacity for the way the household actually uses electricity, including through the more demanding winter months.
