Home & office power backup
OMEGA SERIES Designed for everyday backupA few choices. A backup plan built around you. Find your inverter and battery in three simple steps.
Add appliances that run together. You can adjust each power rating.
How much backup would you like?
Assumes all selected appliances run for the full duration.
Capacity per 12 V lead-acid battery. We calculate how many your inverter needs.
See your matchExample appliance watts and starting multipliers are editable planning values. All selected devices are assumed to run continuously and restart together. Inverter sizing uses the greater of running watts plus 25% headroom or estimated starting watts, divided by a 0.8 power-factor allowance. This is a sizing estimate, not a model’s certified watt or surge rating.
Estimated runtime = battery-bank volts × Ah × 80% inverter efficiency × 50% usable discharge × 85% reserve ÷ running watts. The Ah rating stays the same when matching 12 V batteries form a higher-voltage bank. Battery condition, discharge rate, temperature and appliance cycles change real backup time. No parallel battery strings are assumed.
We shortlist published pure sine wave models with verified capacity and battery-bank voltage. These estimates cover external lead-acid batteries; Lith Tec lithium systems are not mixed with these options. Our team must confirm the battery model, permitted Ah range, charging time and actual starting requirements. No battery brand, price or stock is implied.
