EcoSolaris Romania offers batteries for photovoltaic systems with LiFePO4 (Lithium Iron Phosphate) technology — the safest and most durable lithium chemistry with over 4000-6000 life cycles and 10-year warranty. Available capacities: 5, 10, 15, 20, 30 kWh, compatible with Victron, Huawei, Deye, Solis, Fronius inverters.
Why LiFePO4 — and not standard Li-ion
- ✅ 4000-6000 cycles (vs 500-1500 for NMC Li-ion)
- ✅ Superior thermal stability — they don't light up even if pierced
- ✅ DoD 90% (deep discharge with no lifetime effect)
- ✅ Warranty 10 years / 6000 cycles (vs 2-5 years for old chemistry)
- ✅ No memory — upload/download at any level
- ✅ 96-98% efficiency loading/unloading

How do you measure the capacity of the batteries?
Quick rule: battery capacity in kWh ≈ average evening-night consumption. For a house with a consumption of 5,000 kWh/year (~14 kWh/day), we recommend batteries 10-15 kWh for ~80% autonomy.
| Monthly consumption | PV system | Recommended batteries |
|---|---|---|
| 200-300 kWh | 3 kWp | 5 kWh |
| 300-500 kWh | 5 kWp | 10 kWh |
| 500-800 kWh | 8 kWp | 10-15 kWh |
| 800-1,200 kWh | 10 kWp | 15-20 kWh |
| 1,200+ kWh | 15-30 kWp | 20-30 kWh |
