Someone in the chat just mentioned something out "balanced neutral" , so I'm going to do a brain dump....

In the US wiring standard we have Leg1 (120v), Neutral (0v) and Leg2(120v). Ideally, the neutral makes sure that your 120v devices get 120v relative to the center point.

What if that center point is missing? Let's disconnect the neutral back to the pole transformer and play along... Imagine you plug a 120v toaster into leg 1 and a 120v coffee maker into leg 2. Since both devices pull about 1200watts, even if the neutral is missing you'll get 240v split evenly between the two devices. if we add another coffee pot, L2 voltage will drop to 80v and the leg with the toaster will rise to 160v. They both still add to 240v but they are "imbalanced" relative to the neutral.

If you have lights that dim or brighten when you run the hair dryer or microwave, look for a loose neutral connection in your load center. The clue is that 120v changes but the 240v stays the same when things are switched on/off.

If you are going to order a 32kwh battery, be aware of three things:
1)It MUST use MB56 cells. Several manufacturers are placing two 314ah cells in parallel to make the capacity. This is NOT good engineering practice.

2)You might calculate that you need 32kwh and think you can buy one battery but that battery may be limited to 200amps. If you need 12kw out of your inverter, you will need 250amps and will fall short. In order to get 12kw you will likely need two of any battery.

3)There are many good deals on batteries that do not use JK BMS. If you get one of these you may have vendor lockin when it is time to add more. JK BMS is the universal standard. Vendor A battery will communicate with Vendor B as long as they use JKBMS.

Neighbor found on his property. Shot in the ass and ran away. Could not clear the fence because of his wound. There’s a hot line on top of that too. So poor guy flailed around getting shocked and gouged until he couldn’t do it any more.

Guys ethical kills please!

Brain dump.... when connecting power sources in parallel you should fuse each power source individually. That way if something goes horribly wrong the malfunctioning unit can pop it's own fuse.

Telsa car batteries consist of 7700 individual 18650 or 2170 cells. Each one is connected to it's peers with a 5 amp fuse. If one cell malfunctions it will pop it's own fuse and the rest of the pack continues to operate.

None of the chinese manufacturers are fusing individual LFP 280 or 314 cells. They just strap them together and hope for the best.

Moar brain dump. When you connect PV panels in parallel you can get away without fusing two strings. because even if one string of panels shorts out, they are engineered to accept twice as much current as they produce.

Check the label on any panel and you'll find numbers like Isc 13amps , fuse at 30amps. (Isc is amps short circuit, the max amps the panel can ever make).

However when you combine 3 or more strings of panels now you have a situation where one string could malfunction and the two neighbors could dump amps into it. So when you parallel 3 or more sets of panels you must fuse each individual string at the manufacturers spec (ie probably around 30amps).

There are inline fuse holders that have the MC4 connectors or you can use a combiner box with fuses or breakers.

One more tip... do NOT disconnect MC4 connectors while amps are flowing. Use a shutoff switch or power down the MPPT or inverter before taking MC4s apart. If you take them apart under load they will arc. The arc will destroy the contact surface and about 6 months from now your connector will mysteriously melt.
