I have one of their 6kW units, and in real life it too idles under the advertised 24w at around 19w. I don't know of any inverter currently on the market that comes close to this low of an idle current at this high of an output while also maintaining a 3x surge ratio. Their 12kW inverter can in...

I know the issue was already discovered to be a wiring mistake, but I thought I'd join the others who believe your charging and cutout voltages are a bit high. I would recommend floating at 3.5v/cell (so set 56.0v on your charge controller), and cutting out at 3.6v/cell (set on the BMS for...

While I haven't personally tried this, I have observed a wide range of energy consumption with refrigerators and chest freezers depending on the surrounding room temperature. I believe this has less to do with the efficiency of the cooling cycle (speed of removing heat) and more to do with heat...

Ground your panel frames to the remote ground rod. This will provide a safe path to ground in the event of a direct lightning strike to the array. While it won't prevent equipment damage in that situation, it will greatly reduce the amount of energy coming back to your house in such an event...

Exactly, with "surge protection" in the panel combiner boxes (read, "device that conducts any surge incoming from the remote ground rod to your DC wiring, where it will then hunt for a convenient exit point and fry everything in between"). What happened with his system in that video was exactly...

The particular BMS pictured appears to have a 5A (approximately 17W) balancing capacity. As far as balancers are concerned, that's pretty good and more than enough to keep a large battery pack like this in line once they are balanced; but the batteries need to be pre-balanced prior to being put...

It's really hard to tell what's going on from the supplied pictures. However, I do have a few thoughts. You indicated that the problem occurred when connecting the two banks in parallel. If one bank is fuller than the other, and cell 16 is full (on the lower bank) or empty (on the higher...

Great one-of-a-kind thread you've got going here! Idle power consumption is an often unspecified/non-reported figure that can be quite important and consequential, particularly with smaller systems. Here are the figures I measured from the inverter I'm currently using: 1.) Genetry Solar...

Look at screenshot #2 in the OP for this thread. 92% of the available resolution (the last option) is irrelevant, but because it's there, the first three options (with valuable data) read 4%, 1%, and 2%. If the 92% was removed from the polling entirely, the other three options might read...

The resolution of your data would be much higher if you eliminated the "I have not/do not own" option, thereby limiting the poll to participation only by those with valuable information to share. It is all the "I have not/do not own" votes that are dropping your resolution on the other answers...

It's a shame to destroy such a well-made battery pack like that. There's nothing wrong with it; you've got factory compression, cell support, cell isolation, flexible busbars, welded connections, balance leads—all prebuilt and done for you, with A-grade cells for around the price many sellers...

Wrong question. 9kW of solar is adequate for just about any amount of batteries, because batteries are about harvesting excess energy and storing it for times of shortage (high use/low sun), not some magical balance between battery/solar capacity. Therefore, the amount of battery capacity you...

I wouldn't say that a SEER of 25 is unreal. The Carrier 38MPRB heat pump paired with the 40MPHB head unit gets a rating of 42.5 SEER and 15 HSPF. It is able to heat to full capacity all the way down to -22°F. Anybody have personal experience or thoughts with one of these?

Overall, I think this is an interesting (and potentially good) idea. However, there is one factor I have not seen mentioned yet. Diffuse, overcast weather light comes from directly overhead, regardless of the angle of the sun. By tilting your panels sharply to the south, you will...
