Solar batteries for professional installers.

Only if the inverter supports the battery's voltage class and its communication protocol. Check that the inverter's datasheet lists the battery, or send us the pair before ordering and we will check it against both datasheets.

No. We sell to professional installers and other VAT-registered businesses. Prices and ordering need a trade account, verified against the EU VIES register.

List prices exclude VAT. EU businesses outside Bulgaria with a VIES-valid VAT number are invoiced under the reverse-charge mechanism, with no VAT on the invoice. Bulgarian accounts and deliveries within Bulgaria carry 20% VAT.

Stock comes from V-TAC's own warehouse stock export and is shown with that export's date. When a product has no current stock data it says so — price and availability on request — rather than showing a figure we can't stand behind.

The manufacturer's warranty, passed through in full. Terms differ by product and maker, so each product page lists its own.
