What do you guys think?

Build the cheapest system possible to run a full size refrigerator. & give a recommendation on what brands/ kinds of full size fridges would be best to run solar on ie a linear/inverter fridge or a chest freezer/fridge with no defrost & thermostat. (If your in the market anyway for a fridge)

@Will Prowse can we get an updated recommendation on SCC’s on your website or new videos maybe considering Victrons price drop & the epever BN series is being discontinued.

Ryobi & dewalt both have bidirectional usb-c PD chargers now I would like to see solar recharging of those since lots of us have batteries already.

A 10amp & 40amp are the same price what’s the downside of oversizing? I’m not actually protecting the wires then? I was thinking about using a 10amp inline fuse holder near the panels(to protect the wires) then using a 40amp breaker near the SCC used as a disconnect?

Dam I sent an email picture s-5 & 10 mins later they came back with this response. Customer service is on point “That is an exposed fastened 9" AG panel that our SolarFoot will work excellent on. It will sit in the pan of the panel and fasten into the decking or purlins from there any racking...

Can’t believe I missed this but at 8:30 will gives the settings ?‍♂️

Thanks I wasn’t even looking at the VOC limit great point

Is there an all in one 12V 2,000 watt unit or would I have to go up in voltage?

I’d consider building it on a hand truck YouTube if you haven’t seen it

Thanks this is the kind of recommendation I was looking for

A DIY 12v or 24v system that’s exactly 3,000wh so we can get 30% tax credit. The LiTime 12V 230Ah Plus is almost perfect to build it on but it’s too small (2944 WH) then it seems to jump to server rack battery

I’m looking for the best 24v 100ah with low temp cutoff & think I’m going to go with two 12v100ah powerurus wired in series wish they made a 24v version other option Im considering is two litime “smart” 12v 100ah batteries...

4 x 100 watt panels in series going to 40amp SCC I understand I don’t really need a fuse or breaker but I want a way to disconnect the panels from the SCC near the SCC. Was planning on using a two pole dc breaker but don’t understand how to size it? Also in the future I plan to add more panels...

https://fullbattery.com/collections/dc-hvac Anyone know about these? Window units look interesting!

Shows the adjustment in the video ^

Please this plus grounding

I wrote the 24v thing wrong I’m going to use four HSQ 100 watt panels with a 24v battery. My concern is if I have a switch to disconnect the battery & a dc breaker for the solar panels If they switch off the battery first before the solar panels doesn’t that have the potential to destroy the...

I’d personally rather it be heavier or less AH & way more cycles ?‍♂️ Also couldn’t they just offer both chemistries?

Anyone know if they added or plan to add this feature to the 40amp tracer4215BN ? Dang so if I want one I should snag one now?

Just DC lights a DC fan & a full size inverter refrigerator model # LRDCS2603S 562kwh per year usage per energy guide specs so 65 watts average per hour if my math is correct

Is this a real thing? I see people recommend this but always assumed it was one of those things people read & then just repeated if the freezers are that much more insulated why don’t they just make chest fridges with that much insulation or factory install a thermostat that can change from...

So changing from winter to summer time every year would be difficult?

I’m asking about the length needed

Charge controllers with built in low temp cutoff/protection there’s a couple of options now.

The wire chart I’m reading says #10 wire is rated for 30amps so maybe I should use a 25amp breaker?

bosch vw generator id use a generator from a old VW beetle it can be rebuilt & is bulletproof can be found for $100 ish you will also need the Bosh voltage regulator. To a car battery enloops are considered the gold standard amazon brand nihm are rewrapped enloops FYI Aftermarket version I’d...

It’s a pain in the ass to register them & deal with there customer service but yeah if you jump through the hoops it’s hard to beat the service agreement.

Yes lowest cost would be the best unless there’s something slightly more expensive but significantly better. This is a remote off grid cabin so no inspections.

https://www.gridbase.net/ Not exactly the internet but closest thing I could think of

Thanks! anyone know if this brand is considered ok? Or what kind of cells they use?

You think this one is smashed?

Another SCC with low temp protection 100v maximum VOC though ?

This company normally doesn’t lie but I’d be interested in your test or a teardown of this battery. Wish it was 3kwh so I could get the 30% tax credit if I used it to build my system.

Recommended value for LiFePO4 batteries (12.8V / 4 cells in series) Boost Duration 120 sec. Temp. Compensation Coefficient:0 Over Volt. Disconnect (V): 15.6V Over Volt. Reconnect (V): 14.7V Equalize Charging Volt. (V): N/A Boost Charging Volt.(V): 14.5V Boost Reconnect Charge...

If you were building the system you would use 2awg instead?

It looks like there’s still some new old stock for sale but there also $160+ more than the non TR model

Planning on building a 24v 2,000 watt system very similar to wills using 4 gauge wire for everything except the 24v to 12v buck converter & PV wire. Do you think 10ft of red & 10ft of black 4gauge is correct or can I get away with less...

It can get into the teens like 13-19 fahrenheit

Building my system on paper it’s going to be 400 watts with a 24v 100ah lifepo4 to start out. This is for a hunting cabin in the northeast that will be vacant in the winter time. So I need low temp cutoff protection I also want the system to be hands off so I would rather not rely on people...

Interesting love the simplicity of it

looking for best way to mount 100 watt panels to metal roof, with minimal or no penetrations?

Is there any negatives to oversizing the charge controller on a 400 watt system 12v besides price? I was thinking about going up to a 60amp or 80amp charge controller so I could be more future proofed. I don’t mind spending more now so I don’t have to upgrade it in the future.

Hello I’m wanting to design a solar system to run a 7cu foot chest freezer. The DC sundanzer uses 800watt-hrs a day. Cost is $1900+ shipping homedepot special is $200 but I was having trouble figuring out how many watt hours per day it uses since I Dont own the freezer yet I can’t use a kill a...

The double everything sounded wrong to me too but that’s that will said in his battle born video? ?‍♂️

Thanks I’ll keep that in mind

Then what it searches a database?

Ok so it doesn’t pose a safety issue just a durability issue? Allegedly

Don’t use the charge controllers that come with them. Check out this folding panel it gets good reviews if you don’t need it be really light weight & slim use glass panels like the renogy you posted...

So a 150 VOC max is really 124 VOC max?

That’s what I was thinking that it wouldn’t like the voltage fluctuating What do you think of this converter/regulator...

There are used 245 watt panels with a VOC of 37.7 each for $50 each on FB marketplace close to me. My plan was to use a MPPT SCC with 150voc max could I use 4x panels in series? 37.7 VOC x 4 = 150.8 VOC I was hoping this might be possible since the panels are used? (Northeast USA NY it...

Is there a source for used solar panels like the ones sold from santansolar but on the east coast NY would be best to keep shipping prices down or possibly pick up?

Can you use a standard 110Vac wall toggle switch for low amperage 12Vdc application? Less than 1amp My plan is to wire an off grid cabin for lighting using standard Romex 14/2 e26 bases with 12-48vdc led bulbs I found levington makes a 24vdc 3 amp rated switch but there $12 each Also is...

Thanks these guys look close to me

That’s a great point but with DC appliances isn’t the whole system more reliable because we wouldn’t be using an inverter?

Hello I’m trying to see if it’s possible to run a 12/24v dc mini fridge uses 90 watts no spike when the compressor turns on directly from solar panels. I’m thinking two 100 watt solar panels & some kind of buck transformer to make the power more stable? Any help Innsite would be appreciated. I...

That makes sense figured I was missing something

Dang I was hoping for a more elegant solution than silicone & heatshrink lol

Sorry for the newb question I tried searching before posting but does the VOC fluctuate with how much sun it gets?

Is there no dishwasher you can turn the heated drying & hot water off only using cold water?

Mods delete

These look pretty good from the reviews .27amps at 12volts per bulb https://www.amazon.com/dp/B08X7DWL3H?ref=cm_sw_r_cso_cp_apan_dp_4K3S3XZMYMYXNTW59EY8&ref_=cm_sw_r_cso_cp_apan_dp_4K3S3XZMYMYXNTW59EY8&social_share=cm_sw_r_cso_cp_apan_dp_4K3S3XZMYMYXNTW59EY8&starsLeft=1

Thanks I think I remember Will saying the giandel was 20-25 watts idle consumption according to the spec sheet it’s .8amps

Eg4 12v server rack or litime 230/300ah unless you need the heaters then those won’t work

Don’t you need DC rated switches? https://www.amazon.com/dp/B003AUB65U/?coliid=I2OHTVBQQQ5K3H&colid=3PWZRLTJIXNE8&psc=1&ref_=abl_lv_ov_lig_dp_it

Have an off grid hunting cabin just got the ok to build a 12v 2,500wh system. There’s currently no wiring whats my best bet for 12v LED lights or would usb 5v lights work? I’d like there to be a built in switch so I can just run home run wires from the light fixture to the fuse block. Probably...

A video on the cheapest solar system that will power a full size refrigerator nothing else.

Was looking at the Rheem heat pump water heaters & the EG4 Hybrid AC/DC Solar Mini Split. & that got me thinking does anyone make a heat pump DC/PV direct water heater? Ie no batteries or inverter just plug solar panels in?

Pretty sure your going to need Bosch voltage regulator (can be found cheaper) I don’t think the buck/boost converter you linked is right or necessary for this application but could be wrong

You get low temp charging protection with the rak batteries.

Is there generally considered a “best” company for off grid use?

Email I received back from EPEVER maybe they updated the firmware to have this option? Either way the numbers they sent should work “On the controller there has default setting for 24V Lithium battery,. You need select Lithium battery type and set system voltage 24V on the controller and then...

been researching SCC that have low temp cutoff/protection (so i can use budget lifepo4 batteries) these are the ones ive found so far any victron smart SCC + smart battery sense $30 these look great but are expensive & rely on bluetooth ( i don't trust bluetooth i don't have confidence in it)...

For earth grounding(ground rod pounded into earth) my small 400 watt 24v system at a cabin What gauge wire should I use for the 2000 watt inverter & 40amp charge controller? I’ve read one size smaller than my biggest wire so that would be 6awg. I emailed the inverter they said 12awg & emailed...

Yes I was wondering about commercial products as nearly everything I see is DIY

Getting conflicting info on wills website it states “If you use a Recommended Drop-in Lithium, you do not need to program anything. You plug this controller into your system, and you are done.” But the amazon reviews are all saying I have to put in a custom setting? (If I do need to put in...

What’s the go to racking to attach to the S-5 solar foot unistrut? (Four 100 watt panels)

Lol at the wife that’s funny. I didn’t mean a specialized fridge I meant what’s the best fridge for solar from homedepot/ Lowe’s ect?
