Hi @Neil817
I see you're not a host, so not sure if this is an advertisement for solar system installation.
Either way, I'll mention two things hosts should be aware of:
1) As it's an international community there may not be any tax credits in your region
2) A 5kW inverter and battery system is entry level and may be attractive price-wise. However, with normal use it may not be enough to power heavy equipment like air conditioners as mentioned, and also not heaters, ovens, stoves, dishwashers and laundry machines. One could leave these off the system, or invest in a larger set-up which takes more money and space.
