A user needs enough capacity to take up the load – fans, TVs, light points, laptop, decoder, modems, etc. The 2kVA capacity does better justice to that requirement, than you had with 1.4kVA or even the higher 1.6kVA.
Still, most users want to cap the procurement budget at a bearable level. Staying at 24V (2 batteries) is more affordable for most average users, than going for higher battery requirement, given the current level of battery cost. With the new 2kVA Sukam, you are covered on this count
However you look at it, the Sukam 2KVA/24V inverter is an efficient design, ideal for standard home use and also suitable for small offices.
