Yes, indeed. I don't like the idea of a wonky system, it'll just niggle me when things aren't working quite as I'd like. And a small inverter shouldn't cost too much. It's good to have help with these decisions.

I'm using the solis API at the moment, connecting directly to the modbus is very tempting! Another little project... Does anyone know the behaviour here when the panels are all producing lots of power? Eg 4.5kW on inverter 1 and 1.5kW from inverter 2. * If the house tries to draw 6kW will all...

Thanks for the replies. My first inverter has only 2 MPPTs so I don't think I can connect the second directly to it. And I don't think I need them to coordinate together (eg master slave) - I'm happy for them work independently. Really I just want to get the power from both units used...

I have a similar situation, I'm interested to know how you got on with this. Did it work? Any problems or things you wished you'd known at the beginning? Thanks

I'm thinking of adding a second inverter to my setup. I have a 4.6kW Solis RHI 5G with 9.6kW battery, I'll be adding ~1.5kW additional inverter (no batteries). There are threads elsewhere that suggest this is possible but I have a few questions I'm hoping the community can help answer. I want...

That's a little disappointing. I can't split 3 aspects across 3 strings because the inverter only supports 2. The Tigo website states it should work ok if wired in series...

Hi all, I have a 4.2kW system with 6x West panels (string 1) and 4x South panels (on string 2). These are hooked up to a 4.6kW Solis inverter, and all panels have Tigo optimisers. I'd like to add some more panels to an East facing roof - there's space for 6 but the inverter only supports 2...
