I have 14 panels ( 7S2P, each panel has cca 50V, 10A) that makes 350V, 20A). I was thinking about MPPT EPEVER TRACER 10420AN but it has only 200V, 100A. So can either use another MPPT tracker or buy one more solar panel and connect 15 panels (3S5P - each panel has about 50V, 10A that makes...

Anyone here has any experience with a pure sine inverter? Is it worth buying it instead of Off-grid inverter? Which brand?

I have 14 pcs of solar panels 460Wp each with following param: Open Circuit Voltage (VOC) 40.6V and Short Circuit Current (ISC) 9.24A each panel. How to connect the panels? I can have 7 in series and 2 paralel or 2 series and 7 paralel. Or I can use 12 panels only in one string and 2 in another...
