The demonstration was to show what happens if the current flow through the device is not in the correct direction for a polarised DC breaker. Sometimes I wonder why I even bother with this forum any more.

Why wiring your breaker properly is vital. https://diysolarforum.com/threads/dc-breaker-wiring.14618/

The topic of DC breaker wiring polarity (ie, which side of the breaker is the source and which is the sink) has been raised a few times on the forum. I'm not sure if this clip has been posted before, but if not this is a must for everyone to watch.

It'll probably be all gooble-de-dook to you but you can at least tell if there is any attempt at serial communications between your PC and the charger. Grab a copy of sysinternal's portmon, start it running and then open the solareagle program and see if anything is logged. You can set it to...

The problem you'll face with the portable 'solar generators' is starting power tools. Some tools are well known to be gluttons when it comes to starting current. Check the DavidPoz youtube channel, he has had a few adventures with his saws and breaking inverters. I'm not sure a soft starter...

Jaycar says that one is discontinued but it goes up to 95V on the solar input so that's OK and 50A so covered on the battery output side too. https://au.renogy.com/rover-li-30-amp-mppt-solar-charge-controller/ Only basic options available via the front panel. More detailed programming needs...

They seem to miss badly too, if recent events are anything to go by ;)

OK, they have Vmp of around 30V. You are good to put two of them in series if you want to use a MPPT controller. Both panels would give you around 23A to the battery full tilt, if they ever get there, so a 30A MPPT controller would cover you if you weren't going to add more panels down the...

If the controller is well designed it won't go poof. I think there has only been one instance of a MPPT controller possibly going poof reported on the forum, despite several people, myself included, trying to provoke just that. In my own testing I found that some controllers produce output...

PWM controllers output a bit above battery voltage. They work by, effectively, connecting the panels to the battery and letting the load of the battery pull them down to near battery voltage. You say your panels in series are about Vmp 30, that's a pretty low Vmp per panel so please post a...

Are you dealing with shading? If not the panels in series with a MPPT controller would be a better solution as it would give you more power out at the same sun exposure than the PWM controller would. If the PWM controller is working correctly it shouldn't have gone over voltage so that might...

You can't exclude gravatar.com from its filtering?

Open Chrome's console, go to the network tab, then force refresh the page and see if gravtar is being blocked. I use Firefox (with ghostery) and Chromium under linux. Chromium doesn't block gravatar, but who knows what lurks in Chrome.

It does sound like some electrolytic capacitors vented. The big ones can burst with quite a pop - note this is not exploding just the vent on the top rupturing. It's possible your charger went over their voltage rating. The battery's BMS may have disconnected without you noticing too...

Ghostery's default rules were blocking gravatar for me. Might be worth checking browser extensions etc. Open the brower's console (F12 perhaps), force refresh this page and see if gravatar is being blocked.
