This is how I wire a single string PV array in the combiner box, but it applies to multiple parallel strings as well. In this case, one string for up to 500 VDC. The PV + and PV- each enter into a DIN rail mounted solar fuse holder. In this case, 20 amps. Then they exit the fuse holders and...

Remember, everything outdoors that is metal must be grounded. This means panels, racks, conduits, boxes, etc. Anything outdoors that is not metallic, like ABS plastic boxes or PVC conduit, if having current carrying conductors passing through them must have the ground wire, insulated or bare...

His original post did not contain information on whether he was running AC or DC current from his array. But you are correct if he is running DC current.

Nope, I'm beaten to a pulp. But as I near the end of the line, I do not want things left unsaid. While laborers toil away to come home to a home filled with energized children who want attention and are hungry to boot, plus need a bath, I am able to possibly alert one to the challenges they...

ALL SOLD.

As I think I wrote, put the plate down on the concrete. Mark the holes with a permanent marker. Remove the plate. Use an SDS hammer drill and drill the holes in the concrete. Doesn't matter if you hit rebar, the bit will go though the rebar. Purchase these bolts for concrete...

I'm in So Cal working with a Luxpower 12k. Our TOU is 4PM till 9 PM. I have been able to set up a schedule so I am running off batteries from about 3PM until a little after midnight. I set up the peak shaving from 4PM until 9 PM. I set my batteries to charge from PV first and also from AC...

The UL version is the right stuff and can go into conduits. I bought the same class wire from a different company, but price was essentially the same. In my case, I used 3/0 and did the crimps myself. But I have all of the tools to cut and crimp and heat shrink so it was no big deal. One...

Smoke will always penetrate meats. So yes, when you think you have enough smokey flavor, then switch to electric, charcoal, etc to keep the cook going to your level of completion. Wrapping in foil or butcher paper will also allow further cooking and block out more smoke penetration if still...

Exactly. Think of this for a moment: Utility companies are busy along with corporation building giant capacity lithium storage facilities for nighttime energy demand. Ask yourself this: Do they use cables and wires many feet in diameter because the battery facility is really really big? No...

My electrician earth grounded my panel is all I can say.

Best place for solar doesn't have the same meanings as in the recent past. Many states besides California are neutering net metering and solar should now be though of as a self consumption system equipped with battery backup up system for grid outages. The cost of this system in your locale...

Okay, I did not read the entire thread, to long. This is just information for those persons shopping for a new HVAC system. Our Trane XV20i 5 ton (60,000 BTU) has an LRA of 16 and running of 19 amps. 16 amps to start x 240 volts = 3840 watts to start it up and 4560 watts to run it full...

In Florida they build with poured concrete or concrete block. Very strong. the problem is the roofs still blow off and the homes still flood.

Blue Sea systems MRBF Terminal Fuse Block - 30 to 300A Google it. I have used these for years on the + terminal of battery string.

I shopped at 8 stores. I purchased an East Penn USA made battery. With the New Year's sale still going, it was the best deal for a 36 month no proration and then another 36 months prorated vs. those batteries with only a 36 month prorated warranty and throw it away after 36 months.

I'm in So Cal and our top winds in this area are about 70 mph. The wind rating has to be for 110 mph to be approved/permitted. My arrays required almost 10k-12k pounds of concrete ballast at the base to meet this stress level. They are not big arrays and are comparable to what is pictured...

Build it once. Do it properly and it will last many years. And it will add to your property value.

I think this is confusing to some persons. For example, if you have an inverter that outputs 12,000 watts, then if that output were at 240 volts, the rating would be 50 amps. So the output of the inverter would be a max of 50 amps and therefore 6 gauge wire would suffice to the load panel...

I am in So Cal and my power was transferred to a community power supplier while SDG&E operates the infrastructure. ALL OF THE PROMISED BENEFITS WERE STRIPPED OUT BY THE CALIFORNIA LEGISLATURE AND THE PUBLIC UTILITIES COMMISSION. This was done in the form of a newly created charge authority...

That is not correct. The Radian 4K is 120/240 split phase. the Radian 8K is made up of 2 4K inverter mains, either one of which can be shut off with built in 175 amp breaker and the unit will still output 120/240 split phase. Plus Radian goes parallel, with a designated master and slave...

Cut and Paste from UL: "UL 9540 the Standard for Energy Storage Systems and Equipment, for is the new standard for safety of energy storage systems, which includes electrical, electrochemical, mechanical and other types of energy storage technologies for systems intended to supply electrical...

So far they still have spaces to fill on the lot.

Against the law in California

In San Diego County, we dug well over 500 feet of trenches to run electric and water. The way we did it was to rent a small mini excavator with a 12 inch bucket attachment. Depth to top of conduit is 18-19 inches for code. Grey electric conduit used. Segmented into 100 foot lengths and then...

I think the Pytes Ebox is CEC listed and UL9540a and UL9540 with the EG4. It is listed with the Luxpower which is the EG4.

Will, did you happen to see any Made in USA batteries or battery packs for solar or that will be going into American EV's? The photos are great BTW.

Don't worry too much about that. Even if you flip over the excavator or get it trapped in mud, the rental company sends out a giant truck with a big ars winch and even maybe a bigger piece of equipment and retrieves it. You would not believe the stuff people can do.

The ground mount using the concrete blocks are connected in an uneven quadrangle format. ALL of California is in an earthquake zone. The engineering design met code and there is no habitable structure near it so I guess if it collapses, no one gets hurt. The structure is schedule 40 2 inch...

Please check the following to see if it applies to the new Pytes V5: The Ebox 48100R batteries come with a 2 AWG battery cable. The instructions from Pytes say that only 2 batteries should be connected in parallel, then a single +/- connected to a buss bar. So if you have 4 batteries in a...
