    Our NEW GO-TO LiFePO4 vendor...09.20.21

    Well, I suspect nearly everything imported into the US, particularly from Asian sources, (which is nearly everything we use...) will be significantly and increasingly throttled by supply-chain breakdowns. My philosophy is to purchase double what my current needs are, if I anticipate needing...

    Our NEW GO-TO LiFePO4 vendor...09.20.21

    Actually, lead-acid batteries are becoming increasingly difficult to source, and ridiculously overpriced. They've about doubled in price over the last 12-18 mos.

    Running wire from solar panels to equipment 100 feet away

    So, I just need to check the voltage drop from 48V and ensure it doesn't fall below 34V after a 150' run of whatever gauge cable I end up with? It appears, by using a voltage drop calculator, even 6 AWG wire only shows a 3.55 volt drop over 150' with 30 amps and 48 volts. Unless I'm missing...

    Running wire from solar panels to equipment 100 feet away

    I was scoping out 2/0 welding cable, but I'm now wondering about the 34Vdc charging threshold. I hope that I can charge (4) groups of (2) batteries in serial config (2S4P?) and have the charger see the equivalent of a 48 Vdc load? Jeez, I thought I only had one significant problem to...

    Running wire from solar panels to equipment 100 feet away

    Hello, Iamrich Just found this under "features", but it appears I was too slow. FEATURES • 12000 watt low-frequency inverter 120/240Vac Split Phase output • 60A*2 MPPT solar charger, Voc 250V • BMS port • 36000-watt surge for 5 seconds – 3x surge capability • AC/Battery/PV...

    Running wire from solar panels to equipment 100 feet away

    Hello I'm dealing with similar issues on the off-grid system I'm installing. The shortest distance from the clearing where I might be able to mount PV's to an enclosure (small barn) is 150'. I'm not eager to have both my (8) SOK 206 amp batteries and my 48 volt 12k Sigeneer AIO inverter/charger...

    sigineer inverters and chargers

    Since my (so far) positive experience with Sigineer equipment and their Standard of the Industry customer service, I've also been eyeballing their newly released well pump inverter. It comes in many sizes, their smallest is for a 2hp motor and is the one I'm thinking of buying. They mate a very...

    sigineer inverters and chargers

    Hello I'm a total novice with this stuff but am assembling a whole-house off grid system for our retirement ranch in east Texas. Running my deep submerged water well pump is a priority, along with the AC side of my heat pump, both of which are power-sucks. I purchased one of the Sigineer 12k...

    The Benefits of Three Phase AC Pumps For Solar Water Pumping

    Hello, Johncfii Sorry for the delay in responding to your inquiry. Spent most of the prior week and all the last weekend having our Houston house shown and sold. Didn't realize there were so many details involved, I thought you just showed-up at the ex-wife's attorney's office and signed it...

    Brand new and need assistance in figuring out what inverter I need

    "Life without water" soon becomes death. The common mantra is: 3 minutes without O2, 3 days without HO2, 3 weeks without nourishment. None of those seem like a good way to go. What's a "derecho"? -Guido in Houston (hurricanes, no derecho's)

    Need 240 Volt Inverter Recommendation For Well Pump

    Hello, Birdog I get this feeling you may be a Houston-area ol' boy. Me too, at least officially for a couple more weeks. I'm fixin' to be a bona-fide East Texas porch honky. Just sold the Katy-area crib last weekend. I'm a total novice, moreso than you because I have yet to assemble an actual...

    The Benefits of Three Phase AC Pumps For Solar Water Pumping

    Hello After the tutorials gleaned from this group, and fingers crossed, I took the dive into some components. Prompted by the above discussion on low frequency transformer type inverters leaving less noise signature, I scored a Sigineer MK12W split-phase inverter. It appears to have massive...

    The Benefits of Three Phase AC Pumps For Solar Water Pumping

    Hello, Hedges Once again, I'd like to express my gratitude for all the volunteered wisdom provided. Generally, experts are unwilling to divulge such info. freely. You folks show not only a great deal of expertise, but also a lot of class. You bring up a very relevant point concerning the...

    The Benefits of Three Phase AC Pumps For Solar Water Pumping

    Hello, Johncfii Thanks very much for the reply and suggestions. So, the VFD's I was eyeballing (Hitachi, from a link you posted at top of this thread) 3HP for my 1-1/2HP pump (currently) as you had recommended) showed voltage requirements for 200V and 230V respectively, so I assumed they...

    Help Texas project

    Hello, txNgineer I believe the "renewable" energy systems should be considered additional buffer systems only, not calc'ed as a reliable commodity. From what I've heard, NatGas fueled power facilities were getting pretty slack in their commitments to stay on-line and fulfill contractual...
