I suspect if you're going to run into trouble it will be the voltage/current that the optimizer sees from having the panels in series and parallel. Given those voltages/currents and the specs on the DC optimizer should tell you what's what. That's why I think you'll need to layout at least one...
Lithium Ion is 3.6Vnom, so an 18V pack would have 5s?p cells. So, 18V tools must work in the range of 4V x 5 to 3.4V x 5, or 20 to 17V.
That got me to thinking, we really only need to go from 24V to 20V... so how about 4 diodes in series?
For example, this one is a $2.07/ea and has a 1.1V...
The navy report was interesting reading, particularly the rudder applications. Really would like to know how they would do in replacing a keel on a sailboat (obvious drawback is they consume power, but could it be the next America's Cup advantage?).
Did the Microinverters shut down when the wifi switch was off?
Please do test with the MPP, if the wifi switch does comes on it means that solution posted above won't work.
Thanks for the tip! ;)
Last one I watched was Crash Landing on You, seeing life in North Korea enacted was very different...
If you go to page 10 of this document, you'll see the sizing guide - basically, an Encharge3 can only support so many microinverters. I'm pretty sure it's the same problem/considerations for any AC coupling (ref).
Not sure about "them", but Gates & Hawking have definitely been taken out of context...
FactCheck Gates on Population
Population was one of the elements Hawkings talked about, but that wasn't to reduce the population but to expand to other planets:

3 of my 4 batteries drop from 60% to 33% in a short period as shown to the right. As there was no corresponding power
through the CT, it's once again the issue of the Envoy re-syncing with the actual SoC.
Disturbing as it seems, this is actually an improvement as before the prior s/w update...
Went back on grid a bit ago before the batteries were fully recharged. I only had one blip and that's when I was working away and turned on a big power consumer (forgot I was on battery, I'd been on battery with no issues for so long it took me a second to realize why the leds were flickering)...
Some thoughts:
Make sure the two inverters can work in parallel; sometimes to get them to do so you need to order a special cable.
The 2/0 wire max ampacity is normally around 150 amps, since your max draw is 250 amps make sure there's no single path (e.g. to the BMS) that might exceed 150...
From https://www.ncei.noaa.gov/access/monitoring/wind/maps/202305, it looks like at 10m I could generate power from a wind turbine at 10m during the winter months. Unfortunately, unlike my northern friends, I consume most of my power in summer. From the maps that doesn't look viable. Seems...
That's too kind... more like a million. Solar by itself is great, but those numbers don't include battery costs and that's probably the biggest flaw there. For a stable and reliable grid when you're essentially doing away with 90% of conventional fossil fuels in just a decade you need to...
You can get 2.7v 18650 sized super-capacitors, 39g. So, you could re-purpose a 4 AH 5s2p pack into a 1.1Ah 8s1p pack.
Only a 1/4 the power but lighter and fully recharges in a few minutes. Well, without some sort of voltage regulator, probably only 1/8th the power since the voltage drop is...
My God! It's full of stars!! Bowman jokes aside, You've got some serious skills ... it's definitely not crazy and I thank you for braving all those dangers and sharing. Wow! Now I need to figure out how to follow you.

Just heard on the news that "the 1.9T plan passed the House vote and was headed to the senate", so that "plan" must be H.R.1319; the "American Rescue Plan Act of 2021".
That bill is about pandemic relief, no jobs program I saw in it. I suspect my confusion comes from folks calling it the...
Very true, batteries try to hold the voltage steady, but capacitors (AFAIK) can't. You need another component to regulate the output voltage. But just like a DoD on a battery or a sleep voltage on Li ion there's some bottom limit to V. The reputable vendors (not necessarily the device in the...
Storm Guard
The NWS issued a storm warning here and Storm Guard correctly caught it and shifted to full backup.
Normally I leave the "charge batteries from grid" disabled and have been curious if Storm Guard would override it or not. Not to knock the NWS, but sometimes there is little warning...
Welcome to the forums!
You might find these of help:
What does it mean to have solar panels in parallel and series?
Figuring out how many panels in series and parallel based on your MPPT
What does that have to with proving or disproving climate change?
All those poor conspiracy theorists struggling to figure it out when they publish their research. You don't even need a FOIA request.
They could also have used simple physics.
Let's say like microwaves it can convert ~70% of...
Generator is the cheapest upfront solution. Preferably natural gas if you can get it so you don't have to truck in gas...but if they turn the gas off in the event of an earthquake that might not work for you.
Grid-tied Solar has a payback, so most economical - but... it won't provide power...

Data
30 LED bulbs at 10W each = 30 x 10 = 300 watts
6x 175W solar panels = 1 kW array
Question
Do I need more panels
Do I need more batteries
To answer this you need to know how long you'll run the lights. For example, if you run a 300W load for 4 hours, that's 4x300...
