For this spec, your battery will probably weigh somewhere around 1500 to 3000lb.

there is no such thing as internal battery for 30kVA UPS units and specially for 1 hr.
You need to decide, which one you want, so called 'internal battery' (not requiring additional cabinet?) or 1 hr back up. Can't have both.

30kVA is at the bottom end of the GEDE size range, but the technology is common across the range. As with everything, you get what you pay for, but by dealing direct with GEDE in the UK we paid a fair price for a good product.

It could get you in trouble if the UPS is fully loaded. In most cases I see around 0.9 lag aggregate.
