I have a Max II 10kW bought from Italy. It has performed well apart from 3 issues: 1. I can't get it to reliably charge at 150amp. Some nights it will, others it only does 100amp. I've assumed it is heat related but can't prove it - providing better ventilation does not seem to change the behaviour. 2. The time keeping is poor, losing about 8 minutes a day. Since I'm using it to charge batteries on a cheap overnight tariff this means I need to update the time each evening. 3. It draws about 70W from the mains during the day when it is in SBU mode. This is 1.4kWh per day for the 20 hours of peak rate, or about 60p/day or £219/year. Not the end of the world but annoying - I can spend that money far better than the electricity company. I can disconnect the mains in the morning and reconnect in the evening, but life is too short already. Apart from those issues, the unit is performing really well. with 20kWh of Pylontech batteries I estimate the arrangement is saving me over £1,600 per year.
