Hi @Boguslaw, we do not recommend connecting solar panels of different wattages, as this will result in power loss. We have a blog on this topic, you can check it out. https://www.newpowa.com/a/blog/can-you-mix-different-wattage-solar-panels/ Quote Link to comment Share on other sites More sharing options...
0 Kip McMillan Posted March 7, 2023 Share Posted March 7, 2023 The only way to get the best efficiency is to run with two separate mppts. You you put them all together, you're actually only going to get 300 watts. Quote Link to comment Share on other sites More sharing options...
