An intro to Volt-Amps vs Watts TLDR - in DC circuits VA = Watts https://www.techtarget.com/whatis/definition/volt-ampere-VA What is a volt-ampere (VA)? A volt-ampere (VA) is a measurement of power in a direct current (DC) electrical circuit. The VA specification is also used in alternating...

Good video on Subpanels and Neutral Ground Bonding

Update: This thread will be a common place for asking, answering, and sharing information on the Sungold 10KW 48V Split phase Inverter (which is a rebranded SNRE ASF48100U200-H inverter to the best of my knowledge). Feel free to Ask Answer Post Information in that regard. I'm sure I'll have a...

I inadvertently put too much solar into the input and released the Magic Smoke. Totally dead. I contacted Ecoflow Support and fessed up to my mistake and asked how much to repair. They are going to replace it with a reconditioned unit. That's customer service! Go Ecoflow!

How Ziga Dorkic built a solar powered electric van from a boxy Daihatsu he bought for $100 https://www.abc.net.au/news/2024-02-17/ziga-dorkic-solar-powered-van/103472376 what a shop, eh?

Probably posted/discussed before, but ... here's a ranking of the Sunniest Cities in U.S. I was surprised to see that Denver (where I am) was 20th on the list. I knew we have a lot of sunny days, but was still surprised...

Winter Solstice - https://www.timeanddate.com/calendar/winter-solstice.html

Never before in my 70 years needed them until now due to DIY Solar Projects. LOL! Like: and :) and for now I'm avoiding this King Kong Krimper but who knows...

A 48 VOLT BATTERY PACK WITH CAREFULLY BALANCED CELLS https://hackaday.com/2023/11/28/a-48-volt-battery-pack-with-carefully-balanced-cells/

Oxford claims the world record for solar panel efficiency Oxford PV, a spin-off from the University of Oxford, says it’s achieved the world record for the most efficient solar panel. In collaboration with Germany’s Fraunhofer Institute for Solar Energy Systems, the company says its solar...

**My Solar Power Exploits** (a bit of a follow-up on to a post elsewhere) There was definitely an issue with my old/existing two panels (2x50w) which were connected to my old 40A Charge Controller which was/is just a play-around toy I've had around for many years now. The input to my Ecoflow...

A decade ago, someone knocking on your door to sell you solar panels would have been selling you solar panels. Now, they are probably selling you a financial product—likely a lease or a loan. Mary Ann Jones, 83, didn’t realize this had happened to her until she received a call last year from...

I'm considering this - https://signaturesolar.com/eg4-powerpro-ess-14-3-28-6kwh-capacity-eg4-18kpv-eg4-powerpro-wallmount-battery-9540-pending/ or possibly this - https://signaturesolar.com/eg4-18kpv-hybrid-inverter-system-bundle-15-36kwh-eg4-lithium-powerwall/ Basic difference being the...

I'll try to summarize.... I bought an Ecoflow Delta Pro....thinking that would be most flexible to expand but now I see how limited and costly that is. I've got a couple of Renogy 550W panels hooked to it and was looking to expand those panels as well as a different system. Was/am a bit tempted...

I have 5 rack-mount batteries and while they are somewhat close in SOC and voltage and various parameters I'm wondering is I should 'equalize' them. One battery is generally higher in SOC and voltage and one is generally less in SOC and voltage etc. I'm just learning about how to best manage...

Hoping to learn a lot more about the BMS in my Sungold Rack Mount batteries and potentially building my own battery using the/a Pace BMS... All comments/help/links appreciated! Here's a couple of videos from Off-Grid Garage to get started Spreadsheet comparing BMSs

Not really a review but more of a question. It seems Signature Solar is having a good sale on the eg4 18 Kpv and batteries through the end of the month. I'm reasonably new to this whole field (FYI I'm and EE but my background/experience is in computers/software not in power systems). I'm not...

Please excuse my faulty memory but somewhere I saw a video or post that was talking about starting up or connecting up your system to avoid blowing up capacitors in the inverter or other problems....can't find it again. So what's the best practice to avoid problems when connecting, shutting...

Just blew mine up! Damn!! was hooking up my three new Renogy 550 watt panels hooked the first one up and plugged it in to the River 2 and Yes! Working! went back out and connected the other two panels and boom, the magic smoke left the device....totally dead now. Why the hell doesn't it have...

My ongoing Solar Journey I received this - https://www.amazon.com/gp/product/B0B7N55VF9 a 200 watt panel to use with my Ecoflow River 2 Pro which I've been struggling unsuccessfully to charge daily with the old 2x50 watt panels. It's a bit hazy out at the moment but even now it is able to...

I've been an Ecoflow owner for about one month now. I bought a River 2 Pro and then went on to purchase a Delta Pro with the intention of moving forward with a somewhat portable modular system for my home. I may or may not be selling/moving which is a big part of the consideration. I've been...

I'm considering possibly building a battery... Ran across this.

There’s something about pint-sized vehicles that just gets me going. Anyone can have a van. But what about a van that looks like it went through the washing machine on diaper setting and then a few extra trips around the dryer? Now we’re talking! Check out what I believe to be the unconfirmed...

"True to form, a "strange metal" quantum material proved strangely quiet in recent quantum noise experiments at Rice University. Published this week in Science, the measurements of quantum charge fluctuations known as "shot noise" provide the first direct evidence that electricity seems to flow...

Thought this might be of interest to some... Why Is It Called An Inverter? A Brief History Of Solar Inverters https://www.solarquotes.com.au/blog/solar-inverter-history/

I ran across this video in getting prepped for my upcoming system install and found it very useful in many ways. Lots of info on connecting inverters, panels, batteries, load balancing, testing an install, etc. even though is is different equipment than I'll be installing. Apologies if this has...

I searched around a bit but not sure I got a definitive answer. The question is, 'Is it okay to mix different manufacturer's rack mount batteries in parallel?' Or is that just not allowed. I suspect it's a no-no so once you commit to one brand you have to stick to it if you expand? I also...

Second Life for EV Batteries Time shifting is one of the keys to the solar power revolution. It allows renewable energy created during one part of the day to be stored in batteries for use during a different part of the day. Traditionally, those batteries have consisted of new battery cells —...
