India's commercial and industrial sector still leans on diesel generator hire for backup power — but the economics, the emissions, and the noise are getting harder to defend. With diesel prices at multi-year highs, Delhi-NCR GRAP zones now banning DG sets during pollution episodes, CPCB IV+ emission norms tightening fuel costs, and zero-tolerance noise rules at events and hospitals, the rental category needs a modern answer.
PuREPower BESS rental is that answer. Indian-made, BIS-certified, lithium-ion energy storage in mobile units from 20 kVA / 20 kWh up to 120 kVA / 120 kWh — with stacking for larger loads. Silent operation. Zero emissions on-site. Instant fail-over — no diesel start-up wait. Often lower total cost than diesel for longer rental durations. Rental enquiries are routed through the PuREPower authorized rental partner network across India.
Why BESS Rental Beats Diesel Generator Hire
Silent Operation
Under 50 dB at 1 metre. No diesel rumble. Suitable for residential weddings, indoor venues, hospitals, film shoots where DG is impossible.
Zero Site Emissions
No NOx, no particulates, no CO₂ at point of use. GRAP-zone compliant. No PESO/CCOE fuel approvals needed at venue.
Instant Switchover
Instant fail-over — your equipment never notices a power cut. DG takes 20-30 seconds to start. Critical for AC compressors, lifts, sensitive electronics, kitchens and silent venues.
GRAP-Zone Compliant
Zero on-site emissions makes BESS rental usable across all 32 states year-round — including Delhi-NCR during GRAP pollution episodes when DG rental is restricted.

PuREPower Rental Fleet — 20 kVA to 120+ kVA
Every unit is BIS-certified (R-63005436), IP65-rated for outdoor deployment, with integrated MPPT solar input, lithium-ion battery, and PuREPower App remote monitoring. 20 kVA is skid-mounted for easy van delivery; 30 / 60 / 120 kVA units are forklift-pocket trolley-mounted for site mobility. Stack 2× or 3× for higher kVA needs (modular architecture supports configurations up to ~500 kVA).
For 120+ kVA loads, 60.0 units can be stacked (e.g. 2× = 120 kVA, 3× = 180 kVA; configurations up to 250 kVA are supported). Larger PuREPower 120.0 (Octane) available on enquiry.

What are the rental term options?
Monthly rental is the standard term. Multi-month and long-term lease structures are available for projects with extended timelines. Final terms and rental structure are confirmed at quote stage by the appointed rental partner.
How is the BESS unit charged on-site for longer rentals?
A common approach is a temporary DISCOM connection — the local distribution licensee provides a temporary commercial tap against the basic site documentation. Sites that prefer solar charging typically engage their own local solar contractor for the PV setup and tie-in. The authorized rental partner finalises the recharging plan at quote stage based on site conditions.
What is the difference between kVA (capacity) and kWh (backup hours)?
kVA is the maximum instantaneous power the unit can deliver — this needs to match your peak load. kWh is the energy stored — this determines how many hours the unit can deliver that load before needing recharge. Example: a 30 kVA / 30 kWh Ace will run a 30 kVA load for exactly 1 hour at full capacity, or 4 hours at 25% load. The appointed rental partner helps size both correctly at enquiry stage.
Can I use BESS rental for a wedding or outdoor event?
Yes — events are one of the highest-fit verticals for BESS rental. PuREPower runs at under 50 dB (whisper-quiet vs 70-95 dB for diesel), produces zero emissions, and is suitable for placement close to dining or stage areas without disrupting the experience. Most weddings need 30-60 kVA depending on lighting, AC, and DJ setup. Pre-charged units are arranged by the rental partner for 1-2 day events.
Is BESS rental allowed in Delhi-NCR during GRAP restrictions?
Yes — BESS rental is fully compliant during GRAP Stage 1-4 episodes when diesel generators are restricted. Zero on-site emissions means no contribution to PM2.5 or NOx loads. This is one of the strongest use cases for BESS rental in Delhi-NCR.
What if the load exceeds 120 kVA?
Multiple units can be stacked. Two Octane 120s = 240 kVA. Three = 360 kVA. Configurations up to 500 kVA are supported for large industrial deployments. Submit the load profile via the enquiry form — the appointed rental partner sizes the right stack and confirms availability.
How quickly can a BESS unit be delivered?
Delivery timelines depend on the nearest authorized partner's location, current fleet availability, and site readiness. Metros typically have shorter lead times than remote locations. The final timeline is confirmed by the appointed rental partner at quote stage based on actual conditions.
What documents do I need to submit for BESS rental?
For short-term (under 1 month): basic KYC — PAN, Aadhaar, GSTIN if a business. Security deposit refundable at unit return. For longer-term: above plus a registered rental agreement. Your dealer will share the exact list at quote stage.
Who handles installation and operation training?
Your local PuREPower-authorised partner installs and commissions on-site. They train your team on basic operation (the unit is largely automatic — turn-on, turn-off, monitor via app). For events, partner can also provide an on-site operator for the duration.
Is there a service in my city?
PuREPower BESS rental is fulfilled through an authorized rental partner network across India. Submit a PIN code via the enquiry form; fulfilment for your location is confirmed by the appropriate partner on review.
What happens if the unit develops a fault during rental?
Every unit has remote monitoring via the PuREPower AI Cloud. The system alerts the local partner automatically on any anomaly. The local partner responds per the SLA agreed in the rental contract. A standby unit may be dispatched if on-site fix is not feasible. Service-related charges, if any, are per the rental contract terms agreed with the partner.
Can the unit be purchased after renting it for a few months?
A rental-to-own conversion is one of the standard structures available for long-term rentals, where a portion of rental paid can convert to purchase credit. Discuss with the authorized rental partner at quote stage if long-term need is anticipated.
