Frequently Asked Questions

0704091033 (opens in a new tab)
How long does an order take to arrive?

Items marked In Stock are dispatched from our Galle warehouse as soon as payment clears. Pre-order items are imported on demand - the estimated lead time is 30 to 45 days from the date we receive your advance payment.

Are the prices on the site the final prices?

Yes, for the items themselves. Every price shown is the current per-unit price in Sri Lankan Rupees, and where a lower bank transfer price applies it is shown next to the card price. Delivery is not included in the order total: it is paid directly to the courier when your order arrives.

How do I pay?

Order online and pay by card through our secure payment gateway, or choose bank transfer and we email you our bank details. You can also pay in cash when collecting from the warehouse. Pre-orders are confirmed with an advance payment, with the balance settled before delivery.

What warranty do I get, and how do I claim?

Each product carries a manufacturer warranty - shown on the product page and on your invoice. Every unit we sell is issued a Ray Vault warranty code you can look up on this site, and claims are handled by us locally rather than by the overseas manufacturer.

Can I order in bulk, or as an installer?

Yes. We supply contractors and installers regularly and price projects separately from single-unit orders. Send us your bill of materials on WhatsApp and we'll come back with project pricing.

How do I know the cells are genuine Grade A?

We import directly from certified manufacturers such as EVE and CALB - the same prismatic LiFePO4 cells used in EVs and utility-scale storage - with no middlemen in between, and we can share batch details on request.
