[QUOTE="Vaal, post: 1131426, member: 24036"] Something to keep in mind with panels: if your inverter have 2 mppt inputs you can use only 1 and put all your panels on the 1. At a later stage you can use totally different type of panels on the other input. That sort of bypass the problem of sourcing same type panels at a later stage. But the most important is to never exceed the max input volt on a mppt. On a Sunsynk it is 500V but it is best to rather stop at 450V due to panel voltage gets calculated at 25deg C but panels perform much better at cold temperatures, a clear day in winter at 0 deg can produce up to 10% more than the stated V. And then there is a very good chance of the magic smoke coming out of your inverter and it is difficult/expensive to get them back in. [/QUOTE]
