Takes me all day to recharge 32ah with a 525 watt panel.Good sun doesn’t hit till 1:30 and over about 5:00 Only 1 hour during that time do I get 300 watts from sun.Think again about 100 watt panel getting 20 watts to recharge.Good luck.

You really far north? I have two flexible 100w Renogy panels I use with my camper (it has a rather power hungry 12v compressor fridge built-in, about 40-60AH a day) and never really have any problem with it unless I'm in trees or as on my last trip - heavy clouds (and then only after 3 days). Typical day I get 60-100AH charging with a PWM charge controller.

@ I had 2 renogy 100 watt hard panels and wouldn’t keep fridge on 24/7’with freezer off on my 12v Norcold fridge.It could have been a bad controller. It wasn’t the 100ah battery that’s good for 100% still.So 32ah per day now is fridge only.Freezer is off and haven’t been drinking beer so door has been shut lol Running Ac I’ve seen 10-15kwh per day (4200 watts of panels) but now have an efficient mini-split that out performs 2 rooftop rv ac’s. Summer I seen 50ah drinking beer,have 1 and open door hahaha I haven’t checked consumption with freezer on. Oh and I didn’t know anything till I installed a shunt.Dead bat before morning from 13.2 so may have only been 1/2 charged. All in all pretty neat stuff to know! Glad you system works.

The other day I purchased and put together two 200ah CHIN batteries with a 2000 watt renogy converter and in running my full size fridge in the house for 65 hours. The only downside is that takes awhile to recharge them

I didn’t have room for even some of the 100ah mini batteries… but I was able to fit three 45 amp hour batteries in my cargo area storage bin in my bronco for a total of 135ah. Depending on my Texas weather… I can get 36 hours to about 72 hours on my iceco Apl35 fridge.

Great video ! Love them 12V compressor fridges . We use for camping and transporting frozen food from store to home in summer heat . The LiFePO4 has gotten go good and cheap no reason to use Lead anymore. And for starting battery ,That changing. Our gas scooter had a lead starting battery. This summer I found a NOCO replacement LiFePO4 for it . Put it in and starts a tad faster. I am IN NY so see what colod nights do to it. I won't be driving below 32F . But some nights in NY get quite cold and nice fall day . Once it stays cold I take battery out until spring. I store inside where it is warm . like I do with the lead one. Hoping to get more than 1 year out of tiny scooter battery. I almost went with a AGM type. I was using the flooded type that comes with the acid and when ready you fill it and charge. Now I don't worry about spilling acid . or adding distilled water. I never had to. by time level got to bottom line the battery would no longer hold a charge. My NOCO 1 amp charger has LFP setting. I got the 10 amp one for my bigger 50/100/200 AH ones. just takes longer on big battery. does not hurt them. NOCO chargers shut off on on LFM and go to float on lead type. So many nice LiFePO4 now ! Bogue RV is known in RV industry to be great ! I know long time RV ers and hear it all the time. LiFePO4 is life changing ! wish I got rid of lead years ago. SOTA and POTA users love them ! 73

Getting a 12v compressor fridge was a game changer for camping trips and day trips. And of course very useful for going to Costco (60 mile one way drive for me) while allowing as many hours of recreational activity as you want afterwards. No rushing home to keep the meat cool. We got our 53Quart 12v fridge in 2019 at a cost of $350. A steep upfront cost (though 50% less than a comparable Dometic) but over the last 5 years its paid for itself by never having to buy (expensive) ice in remote areas, and never having to throw away soggy food, or food that got too warm. Because it can be a freezer, when camping for a week or two in a National Forest, if we want to bring frozen meat we can do so, and just bring a cooler for the stuff that doesn't need to be frozen and keep refreezing water bottles to have an endless supply of non-soggy ice. LiFePO4 is a game changer as well. To get 100AH usable lead acid you really need to buy 200AH of lead acid, and you will almost certainly need to replace them more often. When you think about a 10-15 year timespan, you buy 100AH of LiFePO4 once, or 200AH or Lead Acid 2 to 4 times.

@@dorvinion The best part. LiFePO4 keeps coming down in price . and 100 AH is getting smaller !

@dorvinion Ай бұрын

@@robertmeyer4744 The size I feel is kind of inconsequential since it really only matters as it relates to transportation (I love and own two Tesla vehicles with Li-ion batteries that I routinely road trip - LiFePO4 are currently less capable at road tripping) Cost of course is what really matters and its definitely decreasing. I'm very much wondering just what may come of Sodium based batteries for non-transportation needs where weight and volume is even less a concern. Imagine a 90%+ ultra-low pollution grid backed up by 2 or 3 days worth of ultra-cheap residential sodium batteries in everyone's home that's less than two refrigerators in size, yet fire-safe, and non-toxic.

Great Video, however my question is: How long would this battery, with an inverter, run your normal home freezer in a grid down situation?

@dorvinion Ай бұрын

My regular fridge uses 1.2kW a day and it of course does a defrost cycle so that adds to the power consumption A freezer w/o an auto defrost would probably use 1/3rd of that, so without solar panels I'd say 2 days because the inverter uses power too. If its chock full of frozen goods, I'd say maybe as much as 6 days, especially if you set a schedule of every 6 hours turn the inverter on. 200 watts of solar panels (~$100-$200) + 1 battery + 1000w inverter and you can probably run a freezer indefinitely

Agreed! I have a 200W panel that will give me 10A on a full sun day. I also want to see how much power this fridge consumes during the Tennessee summer at 95+ degrees F

@rickgilbrt 2 ай бұрын

@@KM4ACKYes, I expect the duty cycle on the fridge would go up significantly if it were sitting in 95 degree daytime temps, even if it were in the shade. And it would also increase with usage of the fridge, that is, open/close, remove/replace activity. This vid seems less relevant to the battery and more about the fridge performance -- unless the battery has severely underperformed, which it did not.

@stahpit1971 Ай бұрын

Good info! I'm sure they make a good battery. I'm seeing the 100ah batteries for well under $200 now it's really amazing and makes me wonder how long the prices can hold. I was planning on spending 10K for a system in my camper just 3 years ago very happy I waited until now.

@steveharbin5650 2 ай бұрын

Do you need some sort of voltage regulator between the battery and fridge? Or does the fridge tolerate the full range of high to low voltage from the battery as it discharges?

@KM4ACK 2 ай бұрын

It tolerated the slight voltage difference without issue.

@dorvinion Ай бұрын

These fridges can usually run on anything between 11v-24v A lot of them also have a low voltage cutoff of their own to prevent over-discharge of a vehicle's battery
