I've been running two similar HQST 100w panels in parallel and want to double the panels and run them 2S2P, so two roof-mounted flexible panels and two rigid panels as a suitcase. The problem is one of the rigid panels is backordered and now I need it overnight. Can I run this other brand's similarly-spec'd panel?
Bonus question: Any need to fuse each string or is a single fuse ok? I currently have a single 30-amp breaker between the panels and MPPT.
Here are the specs:
Flexible panels in series on roof:
