I’m not sure if the male indicator light is necessary. Switch position is obvious.

I don’t know if this is funny or sadistic.

Previously connected the solar panels, and now running an accessory wire for lights. Thought I was cutting the accessory wire but got the solar wire instead, of course just upstream of the fuse. Amazing how it melted the cutting portion of my crimping pliers. On a bright note I discovered a...

I am installing a small UPS to run my Moms TV and satellite dish during short-term grid down. Measured around a 100W draw. The backup system needs to be granny-proof autonomous so purchased a APS sine wave BR1000MS. Cost was $160 including tax & shipping. The UPS is supplied with an internal...

This topic should go under Renewable Energy Sources however its neither hydroelectric nor wind. The system operates from the charge in rain droplets, not the mechanical energy of them falling. Mentioned 50 watts/M2. or about a third the output of a solar panel. Also looks easy to DIY. Could...

Living in the deep south the majority our electric bill is air conditioning (HVAC). Buying solar panels, battery storage and AC inverter large enough to run the HVAC is not cost effective. Natural gas is cheap here, however running an engine generator large enough to power the HVAC has both...

Yamaha 48V electric golf cart? Solar panels? MakeSkyBlue SCC? I sense a copycat.

This guy makes electronics hysterical. Watch if you need to brighten your day.

Interesting video

What a deal if you need 3-phase power (not my listing) https://houston.craigslist.org/ele/d/houston-apc-smart-ups-vt-series-15kva/7356165044.html

Today was a rare Texas cold morning in the mid-40sF. Full sun and a decent breeze to chill my golf panels. In the usual Texas heat I never saw more than 300-320 watts.

Purchased a barely-used SOK 5.1kwh battery from a member of this forum for my Yamaha AC-drive golf cart. After removing the FLA batteries [toughest part of the swap due to corroded bolts] and removing a couple of brackets there was the perfect space for the server rack case. Made some temporary...

Was cleaning out my dads old stuff and found a 1917 book from my grandfather “Hawkins Electrical Guide #1“. Actually looks useful as it uses language that is understandable by the non-electrical engineer (me). There is even a Wikipedia page dedicated to the book. Go ahead and ask me anything, I...

A fancy neighborhood near me has a promotion, any new home sold in June received a free “Bronco Power Boost” generator with a retail value of $5,900. Googled it and found they will not list the inverter output watts or KWH of storage. Very deceptive at best. Backup power is quickly becoming the...

Diverted from the This guy thinks outside the box adding lead to a LiFePO bank thread I was very surprised to hear this as virtually all UPSs have AGM batteries, and are located inside homes & offices. I have three AGMs under my desk right now. My favorite Harbor Freight sealed battery also...

Am seriously looking at the Harbor Freight 100 Watt Solar Panel Kit to supplement the 400W HQST poly panels on my golf cart during a hurricane. Why I am so interested: I understand amorphous panels work better with clouds. Can anyone confirm? After a hurricane it can be cloudy for a few days...

Grab a screen capture unless you really want to advertise your address. Townhouse is temporary so have not installed solar on the roof. Plus the roof faces southeast so is not positioned optimal. However the golf cart is easily positionable into the sun.

Anybody heard of these guys: https://www.advano.io/ I have a project working with them and am looking for background information.

Humor me on this one. The intent is how to isolate critical/grid-down circuits in an existing breaker panel without major surgery to the wall, and safely isolate backup-power from grid power. And be reversible should I ever sell the house. I have a 3000VA UPS being used as a grid-down inverter...

Video from Robert Murray-Smith. Looks too easy to be true:

Received as a Christmas gift a QVC Special Halo Power Bank 15000. Includes a UL Lithium-ion polymer battery claiming 15AH capacity. Since my office is already converted to 12V battery backup with USB ports I have no need at home to charge my phone during grid-down. There are multiple USB ports...

Laughably unscientific test only as a learning experience, and ensuring the panels work before installing. Was a nice 85F south Texas day with a decent breeze, should provide some panel cooling. Panels were new out of the box, very first time exposed to sunlight. Connected the four panels in...

Looking to purchase a set of Lishen 272ah cells for my 48V golf cart. Will require a 16S BMS rated 50A continuous when on the inverter, however can handle 150A for 10 seconds when accelerating or climbing hills. Charging is only 8A max. Bluetooth connectivity would be really cool but not...
