Good afternoon everyone. I am very, very new to solar! Managed to get a system up and running for 18 months but now find i need to upgrade my solis hybrid inverter. Didnt know at the time but it shuts down if the load is over 5kw. My inverter powers the whole house. I have an 8.5kw shower in a utility that is used occasionally to wash the dogs. Have to switch to grid atm to use the shower. The sunsynk 8kw hybrid says max power is 8.8kw. I found out that it can supply 8.8kw for a short period but i cant find out how short that period is. Could i realistically run a load of 8.5kw for around 15 minutes with this inverter? If not, i will have to go with the fox ess 10.5 but there is a reason why i dont particularly want to do that. Any help is greatfully received and i apologise if this is in the wrong section. Thank you.
