I question the real environmental footprint of any high efficiency device if it breaks and needs repair. Replacement parts have carbon footprints too, requiring energy and resources to be made. And then there’s the broken parts off to the landfill…

It’s very difficult to cut the cord and continue using 25-70kWh per day without either a major lifestyle change and/or converting some devices (heater, stove, water heater, dryer) to fossil fuel. I recommend going with the biggest solar + battery you can afford. You’ll still be connected to the...

Until they come with a 10+ year parts & labor warranty, they seem like a complex solution to a problem while there are proven quiet & reliable, albeit less efficient, products on the market. I don’t need any more headaches.

Tesla is under the Energy Storage Systems category, pages 17-18.

Carbon fiber and plastic We have an all-electric i3 too and love it in SoCal. We get 4.5mi/kWh, it’s quick and very maneuverable, and can hold a lot. It feels a bit like a Tardis that way.

My brother bought 2 of the AC200P - just received them and say they look new. Charging them up now

If you’re planning to mostly run 12V devices, why have a 48V system with 2 DC-DC converters and their associated losses?

Beautiful home and property Do a loads calculation to determine how big a battery needed to cover them for 24 hours. Then calculate how many PV watts are needed to generate that many kWh to recharge the battery during a 2-3 hour window when there is no shading by the trees.

I didn’t have to do that here in Los Angeles with LADWP

I installed 40yr shingles in 2010 and solar in 2019. As part of their service, the installer included in the contract 1 free removal and reinstallation of the panels if I ever need to reroof. See if any of your installers offered or can include this perk in the contract. Then you won’t feel the...

Keep in mind, an 8kW array, for example, can produce around 48kWh/day in the summer in central Cal but only 12kWh on a sunny day in the winter. If you’re avg daily use is 25kWh when the days are short, it will require a lot of panels or halving ones consumption by decreasing energy losses...

Decided to go with a Redodo 12V 50Ah for $199. Now looking for a compact case to install everything.

“Net energy metering is effectively funded by ratepayers that do not have solar, and the tab makes up about 10% to 20% of the average customer’s monthly bill” This is BS. I buy plenty of grid electricity outside of summer. My winter production on a sunny day is 1/4 that of summer. They’re just...

Good point about the Relion cost. For that much might as well go with the SOK. However a ~50Ah battery is easily 10 pounds lighter than a 100Ah

The US changed their policy several years ago from first-to-invent to first-to-file. You have 12 months from filing a provisional application to filing a formal patent application in order to keep the provisional application’s date as the priority date.

Regarding InstaPots, I measured with a Kill-A-Watt meter tonight the energy consumed to cook a Taiwanese beef stew with 100 minute cooking time under high pressure in a 6 quart cooker: 560Wh. For reference, this is an unusually long cooking time in the Instapot; a chicken stew typically runs...

Exactly! I wrote the check for my system - no one else did. What’s not fair to provide them excess clean energy during the day and get credited at the same rate as purchased at a later time?

Regarding passive houses, one issue to be mindful with their super sealed construction is indoor air quality and carbon dioxide build up, for which there are solutions.

Parallel panels is good if some get shaded during the day. Series will reach the turn-on threshold voltage of the solar charge controller sooner and subsequently start charging the batteries earlier.

In the Settings menu, check the value of parameter 36: PV charging current. Should be at default setting of 80A. Someone else had a similar problem and theirs was set to 8A.

Have you done a calculation of how many kWh you anticipate to consumer daily? How many hours of sunlight per day are there on average during the winter? You may want to “over solar” to ensure that even on partly sunny/cloudy days you can still generate enough electricity for your daily usage.

I’d like to build a small power bank with multiple 12V dc outputs (kinda like a DIY Dometic PLB40) for powering a car fridge, hotlogic food heater, etc. Battery will primarily be charged by a Renogy dc-dc charger while driving which I already own. Looking for recommendation of a 12V 50Ah...

Looks great! Where are you at 9300 feet?

Targeting for 5.1kWh of battery, I would prioritize resources towards alternator charging over solar.

I’m referring to the OP of the RV. Upon closer inspection there appears to be 10 panels with each panel appears to have 2 PV cell arrays, so 10 400W panels?

Notice the jumpers across the pack between #1 & #5

24 panels - that’s a big system! I’d like to build one on the rear of the house and calculated I could fit 6 of the 330W Panasonic panels.

No, I was asking Off Gridin’ It

My understanding is structural components like a gazebo don’t qualify for the credit.

Also remember there will be inverter losses, making the 2400Wh consumed by the air conditioner into 2700-2800Wh needed from the battery.
