System Builder
Select your appliances; we calculate the required panels, battery and inverter capacity. Then choose brands and models and prepare your order.
About system setup
Appliance power and daily runtime determine the requirement. Enter device quantities and hours in the System Builder to estimate daily kWh, panel kWp, battery kWh and inverter kW.
The inverter must cover simultaneous loads and motor starting demand, and it must match the battery's system voltage (e.g. 48 V). The System Builder includes simultaneity and startup allowance to find the required power and only suggests models compatible with your battery.
LiFePO₄ offers deeper discharge (about 90%) and longer cycle life, with higher upfront cost but lower lifetime cost per kWh. Gel batteries cost less initially but have shorter life. The System Builder calculates with the LiFePO₄ battery from our shop; if you prefer gel, it is priced during the site survey.
Products sold in our shop, such as panels, batteries, cables and MC4 connectors, carry the same price as the shop, and you can add them to the cart straight from the builder. The inverter is sold on quote at its list price. The panel box, mounting structure and labour are estimates; the final amount follows in a written quote after a free site survey.
