TL;DR: For a bit over $3k (after tax break) + my time, I'll offset half (or more!) of my electric use, and this should pay off in less than 5 years - even in rainy urban Portland! I've been looking into solar for 20+ years, and never had the opportunity to dive in. With the Biden 30% off sale...

My friend’s nearly new, almost totally south facing, completely non-solar paneled roof in Sisters, OR. I just want to get a ladder and start plunking down panels!!!

Was looking for a battery to increase my storage capacity, and decided to take a chance on this one: Vatrer Server Rack Battery. $1023 delivered to my door, in less than a week. I was planning on opening it up and taking a look inside, but don't really feel compelled to. Ordered last week...

So, I have these boxes for my batteries, AIO inverters, etc. If something goes wrong, there's bold wording to SAVE THIS PACKAGING!!! How long do folks hold onto their packaging before recycling it? Wait a month, stress test things, and see if you get infant mortality? Length of the warranty...

I bought a Bluetti AC300/B300, and it's perfect - on paper. My initial experience is troubling - glitchy software, random shutdowns, errors. So, Plan B. Goal: A small critical-circuits only (~ 3kw) inverter, 5kwh storage, and 120v generator input to top off the battery as it drains in a...

https://signaturesolar.com/preorder-hyperion-400w-bifacial-solar-panel-black-up-to-500w-with-bifacial-gain/ I ordered the minimum 10, and have 4 left over from my small install. Great panels, wish I could figure out a use for them. Sold locally.

I did a search a bunch of different ways, and nothing came up, so I assume that's a "NO", but figure I'll ask. I ordered 10 400w panels - minimum purchase. I only need 6 for my "off-grid" installation on my garage, and they're hooked up and generating nicely, no issues. I have no use for the...

Apologies, I searched high and low and only found threads on HOW to get it working, but none discussing WHY. ChatGPT and I juar had a long talk just now and I'm still not sure. Say you have an device (AIO/Inverter/Whatever) connected to N batteries. I assume it reads the BMS SOC and if sees...

I'm building this system - it's a "starter" system to play with. I'd like it to be reliable, easily monitorable. It doesn't have to be expandable outside battery storage. It's mostly to learn, outage backup, and power bill reduction (but not elimination). 120v only - I don't need any 240v...

Haven't seen a definitive answer to this, so I'm double checking with the hive mind: I'm considering getting a Delta Pro + SHP + a few solar panels. It's mainly for critical loads backup, but the solar would hopefully "pay" for the inverter drain, run my fridge, etc. It's also to get my hands...

I'm looking at this inverter: Growatt SPF 3000TL LVM-48P It has a max Solar Input of 4500w. Check. It can work with PV Input 30-115VDC. Check So, 4500/115 = 39 AMPS! 😲 So, I'd need 8awg cable to maximize solar input? Link says 55amps max. Bummer, I just ran 10awg cable. And just read that...

TL;DR: Is this reduction in peak power a result of my panels getting hotter? I didn't check voltages, so don't know if there was clipping going on at the inverter level. We have another glorious day today, hotter than yesterday, and my production curve is already just-slightly-lower than the...
