This may be good (enough) if you have excess solar capacity, say a 200W panel feeding a battery to run a barn light or some such. Not good to maximize photon harvest.
Victron are the best, but not cheap.

I'm kicking myself for not buying last time around...
30A, pwm. cheap, simple, no bluetooth and wifi, lots of voltage settings for battery types, easy for automation (set defaults and go)

Agreed. Victron is the brand one wants... but I haven't seen a deal from then in ages...

Bought many different blue/smart controllers (saving around 20%) from them and all worked perfectly.
Site is updated with new parts frequently. I check once a week or so for new stuff.
From Victron's troubleshooting guide:
6.3.3. Reverse PV polarity
As long as the unit is installed within the published specifications, the PV input is protected internally against PV reverse polarity.
In the case of reverse PV voltage, the solar charger will not indicate an error.
The only way to detect reverse PV voltage is by the following signs:
- The controller is not charging the batteries, the charge current is zero.
- The controller is getting hot.
- The PV voltage is zero, or close to zero.
If this is the case check for reverse polarity using a multimeter by ensuring that the positive PV cable is connected to the positive PV terminal, and the negative cable is connected to the negative terminal.Join The Conversation
