Fine so far, but some issues.
Like others the ShinePhone app often can’t connect, but does eventually. The 6.5Kw battering receives. Charge and releases charge when demand is higher than production, reducing my grid input. That was the primary purpose of getting it. Quite pricy from the solar company at over £3K in the UK, so will be some time before investment is repaid. Another issue is the pre set minimum charge held of 10% , ie I have a reduced working capacity, which in summer would be useful to increase.
