| I just upgraded the solar system at my family's off-grid cabin. It's incredible how much battery technology has improved over the last 10 years. Everyone is getting tired of me checking the panel to see how many watts we're bringing in. Next project, install a shunt and get a Raspberry Pi talking to it over USB. And then I'll be able to build a Grafana dashboard. :) |

| I have a similar project, I'm so overpaneled I bought an electric heater so I could actually see how many watts I brought in during a nice summer day. The victron UIs have an excellent graph history. |

| Really curious about the difficulty of doing a self install with Solar. I'm moderately handy (built a Sauna from no plans) and confident with electrical. Any gotchas? |

| ▲ | soggybread 27 minutes ago | parent | next [-] | | I'm just getting into Solar myself and while it seems like a lot there are some things that you have to do math for. If you've got 10 panels you'll want to find out how to get all that energy to the inverter/mppt without going over the volt/amp limit on the device. This is probably the most difficult part and for everything else there's a huge solar community of people starting exactly where you are. I myself just bought an Anker solar battery and 2 panels that I bring out during the day to charge the battery and it runs my laptop and monitor for the evening after I get home from work. I want to do more but I'm renting so I'm just trying to find ways to do so. When my state legalizes balcony solar you bet I'm going to play with that too. | |
| ▲ | MichaelNolan 27 minutes ago | parent | prev [-] | | I just did an install to add solar and batteries to my shed to power lights and an AC. It was pretty easy. Hardest part was flattening the ground since I did a ground mount system. 5kw panels and 5kwh of batteries. $1000 for the panels, and $1,400 for the battery and inverter. $250 for the ground mount. Plus a bunch of miscellaneous expenses (tools, wires, permits, etc). It would be cheaper if I did it again since batteries and inverters seem to get cheaper every 6 months.

| Or an esp32 to not run Linux and whatnot off of an sd card. Should be more reliable in the long run |

| Where is the cabin? Roughly speaking of course |
| |
| ▲ | _whiteCaps_ 2 hours ago | parent [-] | | The "Sunshine" Coast of BC. Right now we're limited by the charging capacity of the inverter/charger. It can only do 50A in from an external solar controller. In hindsight I should have gone with a 48V inverter/charger to get twice the power going in. On a sunny day we're maxing it out at 1200W for several hours at a time. | | |
| ▲ | dghughes an hour ago | parent [-] | | Hi, from the other coast. I wish I had solar maybe someday. Do you ever watch Artisan Electric from the UK? He tried to run his shop on 100% solar+battery. He ran into a problem where sunny day batteries full shop using power but the panels themselves were throttling. They had no where to send the extra power. He bought a bitcoin floor heater (lol), charged EVs, and some other stuff. https://www.youtube.com/watch?v=evkdqTcMbWM | | |
| ▲ | jvanderbot 15 minutes ago | parent [-] | | Yeah that's the point. Most systems are over producing on peak hours of peak days so they can average out to enough power on lower light days. You can buy more batteries, but if you don't have batteries it's waste. |
