I am planning to get 400W panels, and use Tigo DC optimizers to comply with Rapid shutdown device (RSD) requirement and monitor the system.
the panels are
Axitec 400W Solar Panel 108 Cell Bifacial
Short circuit current Isc: 13.79A
Open circuit voltag Uoc: 37.07 V
RSD are required at each individual panel level, but can I use Tigo TS4-A-O (700W) or TAS-A-S (700w),
and parallel/series 2 solar panels into them and still able to comply with RSD requirement?
That way I can cut down the cost of RSD devices, since the only reputable 400W optimizer I see are from SolarEdge P400, and they are not cheap.
There are no shades near the pv array, so I don't need to optimize every panel.
