Battery Storage & Backup

Battery storage is optional. D&J Innovance supports battery banks for wind systems and hybrid Wind + Solar configurations. The calculator below sizes backup from your load, voltage and required backup hours.

Battery options

Three common battery types.

The supplied 3 kW/5 kW technical materials list lithium-ion, LiFePO4 and tubular lead-acid compatibility, with LiFePO4 marked as the preferred option in those datasheets. The quotation calculator does not force a chemistry selection.

Battery option

LiFePO4

Pros: Higher upfront cost; strong choice where frequent cycling and longer service life are priorities.

Selection: Final choice depends on required backup hours, cycling pattern, available space, maintenance preference and budget.

Reference pricing: 24 V × 100 Ah = ₹25,000. Larger banks are estimated proportionally on this website; exact commercial battery pricing should be confirmed at quotation stage.

Battery option

Li-ion

Pros: Compact and energy-dense option; final battery pack configuration depends on the application.

Selection: Final choice depends on required backup hours, cycling pattern, available space, maintenance preference and budget.

Reference pricing: 24 V × 100 Ah = ₹25,000. Larger banks are estimated proportionally on this website; exact commercial battery pricing should be confirmed at quotation stage.

Battery option

Tubular Lead-Acid

Pros: Traditional backup option with lower upfront pricing; heavier and needs suitable maintenance/ventilation.

Selection: Final choice depends on required backup hours, cycling pattern, available space, maintenance preference and budget.

Reference pricing: 24 V × 100 Ah = ₹25,000. Larger banks are estimated proportionally on this website; exact commercial battery pricing should be confirmed at quotation stage.
