Solutions

Send your load profile, inverter preference, and project country. We return a practical configuration path you can quote, not a brochure pick.

Residential backup and self-consumptionResidential backup and self-consumption. House with roof PV and indoor battery cabinet; show practical installation spacing.

Residential backup and self-consumption

Best for: Installers serving homes with unstable grid supply or high evening tariffs.

What we need from you: Monthly bill, critical load list, inverter brand, and backup hours target.

What you receive: Matched battery/inverter shortlist, one-line diagram, and document checklist for quotation.

Not included by default: Local permitting, AHJ approvals, and on-site installation labor are yours or your installer’s scope. We do not guarantee utility export rules or incentive eligibility—those stay with the customer and their engineer.

C&I peak shaving and demand controlC&I peak shaving and demand control. Factory roof + outdoor ESS cabinet; include electrical room or transformer context.

C&I peak shaving and demand control

Best for: Factories, cold-chain operators, and commercial buildings with demand-charge pressure.

What we need from you: 15-min load profile, tariff structure, grid limits, and operating schedule.

What you receive: Cabinet or container class recommendation, control logic, and expected dispatch window.

Not included by default: Utility interconnect studies, relay settings, and EMS logic that must be signed off by the local utility or a licensed engineer in your country are not something we substitute for. We supply hardware and factory documentation; grid applications stay with you.

Hybrid systems for weak-grid regionsHybrid systems for weak-grid regions. Remote site with PV, hybrid inverter, and battery enclosure in one frame.

Hybrid systems for weak-grid regions

Best for: Sites facing frequent outages, low grid quality, or diesel dependence.

What we need from you: Outage pattern, fuel usage baseline, PV resource, and priority loads.

What you receive: Hybrid architecture with battery reserve policy and commissioning checklist.

Not included by default: Genset overhaul, fuel contracts, and civil works are outside our supply unless written into the PO. Runtime figures are modeled; field performance still depends on installation quality and maintenance.

Integrated PV + inverter + battery deliveryIntegrated PV + inverter + battery delivery. Single-line sketch beside installed system photo; keep labels readable.

Integrated PV + inverter + battery delivery

Best for: Distributors and EPC teams who want one supplier interface for core hardware.

What we need from you: Target country, compliance scope, shipment plan, and preferred commissioning model.

What you receive: BOM proposal, lead-time band, and staged document pack before shipment.

Not included by default: Structural mounts, long cable runs, third-party monitoring subscriptions, and customs clearance inside your country are quoted separately or handled by your forwarder unless we agree otherwise in the contract.
