I suppose there would be some mathematical way to gather approximate (trendline) energy usage using that data... so long as it can store enough data points for several weeks. hmm. Trying to think how I could get energy data from that easily. Maybe just an excel sheet with a multiply formula...

Logging to what? How would I get that data? OffGridInTheCity's reply makes it sound like I would have to set-up a network. I appreciate the thoughts! I am ideally trying to keep this as simple as possible. It's for work, and this I cannot afford to spend a bunch of time fussing around with...

I assume this would entail a good deal of friggin around? Like would it entail soldering components together and/or programing. Both are likely off the table for me. Do you have any links to descriptions of this process?

No, I just genuinely don't know how current can be managed without affecting voltage. I assume it must have some effect on the charge efficiency. In a basic electrical scenario, to increase current through a given resistance, voltage is increased. So how does a charger increase current without...

I know this was about gen-set efficiency and not charge efficiency per se, but how does a charger (such as the one in the video) regulate charge current without changing charge voltage?

Hi all. First post here. Looks like a good resource. I manage a couple off grid cabins that run some loads off a small (2, 280 watt panel) solar system with 24v, 400Ah lead-acid battery storage. These cabins get rented, and it's tough to know how much energy is being used. We're looking to...
