Frequently Asked Questions
What capacity range does VoltraSys supply?
Standard cabinets run from 50 kWh to 200 kWh, and several cabinets can be paralleled for larger loads. Most commercial and light industrial projects fall between 50 kWh and 500 kWh. Above that range we size the battery, inverter and switchgear together with your engineering team before quoting, so the interfaces are fixed before the order.
Can your system be added to an existing solar installation?
Yes. Our hybrid inverters support AC coupling to an existing PV inverter, and DC coupling where the array is designed together with the battery. We check the existing inverter model, string configuration and export limit before recommending a topology, because retrofits usually fail on compatibility rather than on battery capacity.
What payback period should I expect for peak shaving?
On commercial tariffs with a clear peak and off-peak spread, peak shaving typically cuts demand charges by 15 to 30 percent and pays back in two to four years. The real number depends on your load profile, tariff structure and daily cycle count, which is why we size against twelve months of interval data wherever it is available.
Do you offer OEM and ODM programs?
Yes. We support private labelling, enclosure and connector configuration, BMS protocol adaptation and custom documentation packages. Minimum order quantities depend on the level of customisation, and tooling or certification work is quoted separately. The same engineering contact stays on the project from specification through pre-shipment inspection to delivery.
What is the lead time and what ships with the system?
Standard configurations ship in four to eight weeks from order confirmation. Each shipment includes the datasheet, IEC and UN38.3 documentation, packing list, installation manual and commissioning checklist. For projects that need grid-connection approval, we prepare the technical file your installer has to submit to the utility.
How do you size a system without a site visit?
We work from twelve months of interval load data, utility bills and a single-line diagram, which is enough to size most commercial systems remotely. If that data is incomplete, we ask for one week of logging on the main incomer. A site visit or third-party commissioning check is arranged for larger or retrofit projects.
