# The inverter can only generate 5kW of AC power. IFF the battery is not-full, it can generate 5kW of AC _and_ charge
|
|
# battery at up to 6.6kW, which saturates our 8.46 kW of PV
|
|
#
|
|
# So, preventing the battery from getting full too early on a sunny day will increase our overall yield, because the
|
|
# inverter won't have to derate the PV power to 5kW.
