Battery storage
Power That Doesn't Stop At Sunset.
Storage buys resilience. Sized from the loads you truly need during an outage, it keeps a home or business running without overspending.
How storage works
Solar By Day, Battery By Night.
During the day your array serves the load first, then charges the battery, and only then exports any surplus. When the sun sets or the grid fails, the inverter draws from storage to keep selected circuits alive.
That sequencing is why hybrid systems need a design decision up front: which loads are essential. Lights, fans, Wi-Fi, a refrigerator, security or medical equipment are inexpensive to back up. Air-conditioning and pumps change the arithmetic sharply.
Batteries add capital cost and have a finite cycle life, so they rarely shorten payback on their own. What they deliver is continuity — and that is a genuine benefit worth paying for deliberately.

Battery capacity
Select essential loads
Estimated backup scenario
18.6 hrs
Indicative runtime for 435 W of selected loads from a 10 kWh battery, assuming 90% usable depth and 90% round-trip efficiency.
Calculated from your selected load assumptions — not a guaranteed backup duration. Real runtime depends on actual load behaviour, battery state of charge, temperature and system configuration.

Chemistry
Lithium vs Lead-Acid.
| Aspect | Lithium (LFP) | Lead-acid (Tubular) |
|---|---|---|
| Usable depth of discharge | Typically ~80–90% | Typically ~50% |
| Cycle life | Several thousand cycles | Few hundred to ~1,500 cycles |
| Footprint & weight | Compact, lighter | Bulky, heavy |
| Maintenance | Essentially maintenance-free | Periodic water topping needed |
| Upfront cost | Higher | Lower |
| Cost per usable cycle | Generally lower over life | Generally higher over life |
