Flooded tubular lead-acid
Lower upfront price and a familiar Indian service network. Needs ventilation, floor space and periodic maintenance.
Best for: budget backupGel / sealed lead-acid
Lower maintenance and spill resistance, but still heavy and sensitive to charge settings and deep discharge.
Best for: cleaner lead-acid installationLiFePO4 lithium
Compact, high usable capacity and integrated battery management. Higher upfront price; inverter communication and warranty support are crucial.
Best for: daily cycling and premium backupThis simple energy calculation includes usable-depth allowance only. Inverter loss, surge load, temperature, ageing, cable sizing and manufacturer rules must be checked by the designer.
Minimum nominal storage1.9 kWh
Approximate 48 V equivalent40 Ah
What to request in writingCompatible inverter + BMS · usable kWh · cycle warranty · installation protections · replacement terms
A battery is mainly a backup/resilience purchase in a flat-tariff home. It can increase usable solar after sunset, but it also adds cost and eventual replacement—so do not count its full price as automatic bill savings.

What to send for an accurate quote
- Your latest electricity bill — the sanctioned load, consumer number and last 3 months of units decide the correct system size.
- A photo of the roof — ideally from two corners, so shadow from water tanks, parapets and neighbouring buildings is visible.
- Rough shadow-free area — about 108 sq ft per kW is needed, so a 3 kW system wants roughly 325 sq ft clear.
- Whether you want outage backup — this is what decides on-grid versus hybrid, and it changes the price materially.
What happens next: a phone conversation, then a free site survey, then a written quotation listing the exact panel model, inverter model, structure and ALMM/DCR eligibility. Nothing is charged before the survey.
