I have Bluesolar 100/30 and 150/70 (Easysolar)MPPTs connected to the same battery bank in 24V system. I have set both MPPTS to equalize in every 10 days. this is an offgrid installation. Noticed something strange with VRM and 100/30 charger:
- For some reason VRM does not show equalization in status graph, even though Voltage goes up indicating that equalization is actually happening.
-100/30 shows strange Bulk-OFF-Absortion state switching right after equalization. in one instance it ended to fault stage and was not able to recover from fault and I needed to disconnect and reconnect to get it working again.
150/70 seem to work fine, but not showing equalization in VRM
100/30 graphs:
150/70 graph (sorry that the panels are a bit misaligned) :
Any idea why the state does not show equalization in VRM or why 100/30 is behaving this way?
I won't be on site for a couple of weeks , but I would be happy to receive any feedback on this behaviour. Both MPPTs have the latest FWs loaded and have identical settings.
