not exactly true. If you run the mini split to where the return air of your central air is, you reduce the return air temp which in turn, reduces the load. I am not exactly sure how much effiicency you'd loose, but aint bad. The water heater is just the easiest of the bunch to do, but...

Net metering varies from localities. I'm grandfathered for at least 10 years for a 1:1 swap.

I use a 7s balaencer... And it seems to do just fine working with a bms. On a cycle it will come on here and there, but it is way less than when I first installed it. Plus I like the little led indicator lights. I don't think I'm hurting too much of anything, and it lets me not have to kick in...

Don't disgree, but these are also professionals. I'd gander to say that half the cheap "USB charge packs" sold by some random name are re-used cells. Wasnt that a big scandal of used cells being re packaged as "new" a few years back? Yes, your right, should you use second hand stuff for...

Aint that the promise of block chain technology?

Oh that is something. It's like inverse solar production pricing. The issue would then be how much can you store in that short periods of time between 1230-1500 I'd consider some of the high charge rate batteries, which is generally opposite of what people use here which are slow charging all...

Your doing it reverse. You want to change it to battery in the daytime, and charge while you sleep. As far as I'm aware for every implementation of time of day use, it is more expensive during the day, and cheaper at night. Thus you want to charge at night and use during the day. There are even...

There are DC powered heating/cooling options as well.

think of the solar as a "pre heater"- it pre heats the water before it goes into the main tank.

Largest limiter on this is the battery capacity. And you still have to make sure you have the grid interconnect if you actually want credits from your utility company. I only get credits with mine in a 1:1 swap.

As far as your question goes: (and answered by someone) delivering power back to the grid is where the problem exists. In fact in my area the power companies are specifically putting meters in which have live data feeds- one possible reason: To know when your pushing power back to the grid with...

I had a bunch of 18650's that I just kinda.. well lazy to shuck them from their cases. Finally did it. These were (most) of the cells: Brand: LG Model: LGAAS31865 Capacity: 2200mAh Rated Voltage: 3.60V Nominal Charging: 4.20V Maximum 1075mA Standard 2150mA Maximum Discharging...

Here's a fun one. I've been using a Goal Zero Guardian- with a Yeti DC to DC charger for over 5 years. Maybe 7... It has a cigarette lighter, to a power brick. The power brick goes into the solar feed port of the Guardian. And the guardian charges the battery. Its worked pretty much...

Ahh. I do recall for all the nickel flat ribbon that is used that it actually has a pretty high resistance value as compared to copper. So.. equal length headers like for an engine so that the flow rates are all matched across all ports. I get the concept, but does it make that much of a...

My guess is that his distribution wires from the BMS to the bike controller were probably ok- if there was resistance there, the wires would get hotter and hotter and cause more resistance, which would cause the batteries to actually have less draw. I forget the math of things, but the general...
