Questions buyers ask
Is it certified to EN 50171?
No. The system is designed to the factory’s national standard. Tell us the code your project must meet and we will confirm what can be supplied.
Can the unit carry our brand?
Yes. Logo, front panel, packaging and manual can be supplied under your brand. Minimum quantities and lead times are on the OEM / ODM page.
What do you need for a quotation?
Load in kVA or kW, input voltage and phases, output phases, the backup time you need and where the unit will be installed. If you are unsure, send what you know and we will ask for the rest.
