Start with what you want to power. Then choose compatible equipment.
1. List your essentials.
List each appliance, its quantity, power rating and hours of use. Tell us which appliances must stay on during an outage. Fridges, pumps and other motor loads can need extra starting power.
2. Decide your backup hours.
How long should the essential loads run without grid power? Inverter power, measured in kW, and battery energy, measured in kWh, answer different questions. A larger inverter does not automatically give longer backup.
3. Choose how to use solar.
You may want battery backup, solar plus battery storage, or a small array to help recharge a battery while retaining grid power. Choose your goal in the calculator; ask our team to confirm which inverter supports it.
4. Match the equipment.
A 24V battery system needs equipment designed for that voltage; a 48V system needs compatible 48V equipment. The exact operating voltage range, battery communication and current limits also matter. Share the model labels of any existing equipment.
5. Check the roof and panels.
Tell us your usable mounting area, roof type and shading. Enter a panel wattage assumption in the builder; our team will confirm the exact panel specification. The final string arrangement depends on the exact panel label and the inverter’s PV limits.
6. Confirm the complete quotation.
Ask for the equipment models and quantities, warranty terms, accessories, protection, mounting, delivery and installation scope. Confirm which items and charges are included before paying.
The calculator shows assumptions and flags missing specifications. A site survey helps confirm mounting space, loads, cable routes and installation requirements. It does not replace the final technical design.
