Sadly, this happens more than most folks realize. Just 3 weeks ago I was in Central TN, where a solar contractor delivered the goods, connected the inverter and battery, but failed to install the solar panels. For over 6 months, the homeonwers had to fire up their generator 3 or 4 times a day to keep ...

The Atlas batteries are UL listed and also include a BMS. (Battery Management System). Most current LiFePo4 batteries include BMS - which has features such as over current disconnect, over charge disconnect, RS485 and/or CANBUS comms for inverter communication/monitoring, cell balancing, and visual display ...

The Atlas LiFePo4 battery is UL listed by the manufacturer, but not under the ATLAS brand. it IS, pending under the ATLAS brand at the present time, however - just checked with Atlas! ------------------------------ Joe Utasi PV Solar Consultant Cinci Home Solar, Keowee Home Solar, DIY Solar Helper ...

no error. the pricing is legit. Talk to Darrell Rasmussen at AtlasEnergySolutions dot com and see for yourself. I pride myself on being a smart shopper. The next best pricing on LiFePo4 is from YIY in China, but the ocean freight creates a situation where it only makes sense if you're buying 4 or more. ...

Turns out the Sol-Ark includes a wifi dongle and software app that you can download to your phone to see every single aspect of operation in REAL TIME. It's beautifully constructed and is just as "intuitive" as the front panel display on the inverter!! ------------------------------ Joe Utasi PV Solar ...

30 Older panels 7500 watts = $3750, racking $1000, 12K Sol-Ark inverter $7000, 3 10KWH ATLAS LiFePo4 batteries $7500 . Inverter output is 9000 watts continuous, so lets use that as the divisor to get cost per usable off-grid watt. 3750+ 1000+7000+7500 all / 9000 = $2.14/watt of useable 240VAC. Keep ...

I installed my very first SOL-ARK OFF GRID system over the weekend. A sol-ark 12K. 3 strings of 10 panels and two 10KWh LiFePo4 batteries (owner will expand to 4 total as budget allows). VERY nicely designed system that includes CAN BUS BMS comms to the batteries. Hooked it up, turned it on, programmed ...

In general, the NABCEP "Solar Installation Professional" Certification is the golden ticket for designing and installing the typical residential and commercial solar installation in most states around the country. The test is quite comprehensive and the fail rate is rather high!! The test includes a ...

Mr. Fitch, I got a good laugh from your response! I sure didn't mean to "mislead" anyone. The space comparison is legit. The foil stops the radiant energy. The IMPORTANT thing is the point you make that it's NOT one or the other (insulation vs. foil) It's just that with the addition of the foil you ...

Steve Kawell has it exactly right. I live off-grid, with a well insulated, tight home. I have 4 mini splits, and 90% of the time just ONE of them in the main room is all we need. Mini splits can be purchased withe SEER ratings of 27 and HIGHER. Higher seer means better energy conversion efficiency. They ...

solar tracking, if used in a LARGE, array, is generally setup as E/W tracking only. By using only a single axis, more panels can be moved, with less energy, less cost, and better wind resistance. 2 axis tracking is a VERY expensive installation cost, and on a UTILITY SCALE would be cost prohibitive. ...

The radiant barrier film is NOT a moisture barrier. It is perforated to allow moisture to move. After 10 years in my attic there are no signs of any kind of moisture buildup, mold, mildew or water staining. IT is an EXCELLENT product to reduce energy losses and has been on the market for over 25 years. ...

With all this talk about insulation values everyone seems to be missing one VERY important concept. Insulations doesn't STOP heat flow. It just SLOWS IT DOWN!!!! Do you have a 2nd floor that is always HOT in the afternoon? Even with 20 inches of insulation in the attic?? Of course you do. There is a ...

Looks like a simple but effective idea. But what about humidity buildup during the winter when the house is closed up? Do you have an ERV in the house? I do something similar with my heat-pump water heater. Vent it into my recreation room during the summer, and out the sill during the winter. It DE-humidifies ...

Stu is right. Everything we own, including clocks, tvs, alarm systems, gdos, doorbells, washer/dryer, microwave, induction cooktops, water heater, etc. use power even when "off". We can unplug a lot of stuff, but face it, there are some items that It just doesn't make sense to disconnect. I live ...

I agree with Mr. Fitch. I live off grid, and have done so now for a little over 2 years. Doing this is a SERIOUS comittment in terms of time, money and effort. Despite what you may read, it is an ONGOING experience and it doesn't matter whose equipment you use. YOUR installation will be UNIQUE and have ...

I also have a Rheem heat pump water heater. I just set it to heatpump ONLY mode. It only uses 400 watts when running. Best of all, during the summer I use the exhaust to cool a rec room in my basement. In winter I dump exhaust out a sill plate vent. I have an 8KW array with a "bonus" array of 4 extra ...

I have a 30KWH LiFePo4 battery bank (3 10KWh units in parallel). Mine are from YIY in China. I have my Magnum system set up so that the charging stops when the charge current (total) drops to 10A. This gets me to 99%, sometimes 100%. My YIY batteries never heat up, whether charging at 75A or discharging ...
