Hi Everyone is there anyone that can help with a problem I have ... I have a Sunny Island 6.0h / Sunny Boy SB4000TL/21 - I have 16 cell 200amph lithium iron battery pack, and 4.5 kW of solar panels. Currently off grid for last 4 months everything working fine apart from one small problem concerning Sunny Boy ... Sunny Boy is set to grid tie and I need a grid guard code to change to island mode. No installers in my location can anyone help on how I can change from grid tie to island mode. Thanks in advance.
