Propane tanks are normally installed with plastic pipe underground and the transition to metal pipe most of the way up the vertical run...

I don't know about inspection requirements. But T-class fuses can be a source of fire, so I'd be inclined to put them in one or more...

I'd bet that's a "yes". If so, I wonder if they'll apply (all or some of) the tariff to storage systems containing Chinese BMSes. If...

If they're in a welded-jumper assembly, inside a completed storage system, with neither the system being suitable for building into an...

Two or three decades ago, when solar panels cost an arm and a leg, adding a tracker to get a 40%ish boost from a couple panels was a...

That's my understanding, yes. Typical transmission lines run AC currents per-phase-conductor in the 750A ballpark during normal...

Also: it won't be a significant issue unless you ground those many miles away panels. The two wires for each string run close enough...

It's not the DC current up one and down another of the three lines of the three-phase transmission line that's an issue. The three...

Perhaps the Nest devices were dependent on house line power and that had failed when the flaw in the power system started, sufficiently...

As I understand it: - Lithium chemistries have very low self-discharge - virtually zero, and especially just after fully charged. - So...

As to what happens to the "overflow": It heats the panels, but doesn't damage them. If the controller rejects the power by no longer...

As others have pointed out, you really need to precharge (for SECONDS) with the resistor to prevent catastrophic damage to the...

What rebate is this? Something special for Illinois? (I thought the federal residential rebates only applied to equipment purchased new.)

Just cranked up the Harmon pellet stove a little farther at the townhouse on the east side of S.F. Bay. Not solar there and moving out...

It's an ordinary 3-phase panel fed from a 240V "high-leg delta" utility feed. The neutral is fed, not from the midpoint of the phase...

Specfically: - MUTUAL inductance between the two halves forces the current from transferring power between L1 and L2 to be equal and...

Well... The conclusions are right but I'd phrase it differently. Confusion arises because the two lines are at opposite phase, so if...

Because one form of nerd humor is to take a joke literally and deadpan extend it one or a few steps further. Sometimes it gets...

Nah, they just made the sun arrive at work an hour late, moving that hour's production to the afternoon. You'll have it back by the...
