Lithium Battery Upgrades:
This type of lithium battery is highly expandable (up to 160 batteries) but consideration must be made for racking and correct cabling.
Battery upgrades should be done within 6 months of purchasing to avoid significant age differences. Warranties are affected if upgrading outside this range.

Solar Panel Upgrades:
We recommend a maximum of 24 panels on this controller. For further expansion, additional controllers can be wired in parallel.
This controller has 2 MPPT inputs. This is great for expandability as both arrays are completely independent so they can be of different size, facing or panel type to each other.

For all options please get in touch with the team for advice and a discount on your upgrade parts.
