I have a new-to-me 2009 Freightliner step van that spent its previous life as a LDV-made tool truck. I'm still building basic knowledge and trying to understand what I have before I get on the road full time in a little over a year. On the roof are four, factory-installed Go Power! GS RV 110...

Wow, that speaks highly of your emotional intelligence. Thank you. Though I didn't necessarily care for all of the back-and-forth, I did get meaningful info out of the discussion from both of you. I will be converting a step van into a RV so my takeaway was I would probably be better off...

I appreciate the report. With your alternator putting out over 200-amps, are you concerned you're "wasting" some opportunity? The price on these seems hard to beat when compared to over $400 for the 50A and 60A versions from Sterling Power. I ask because I need to make a similar decision. I...

@Darkstar the thread I linked to states not to trust the rated energy use. Consumer Reports showed actual was less than other lower-rated fridges, and the guy posting was seeing <30W/hr average for the 20cuft version. He also wrote "actual power used is about a kw a day with the inverter no load...

I follow this #vanlife YouTube channel and they recently posted the details on their off grid system. It uses many of the products discussed on this forum including Battle Born batteries, AIMS inverter, Sterling Power Batter to Battery Charger, Sterling Power ProCharge Ultra, Victron Power...

I was able to clean the combiner box and install a new rubber gasket, as well as take open circuit readings. I have four panels. Each side of the vehicle's roof has two panels wired together in a combiner box under a panel that isn't accessible unless I remove the panel from the roof. From that...

Dzl explained it better than I did. Dollars saved on fridge become dollars invested in solar generation.

Thanks and correct. I measured the voltage at the input terminals of the SCC. I see where I went wrong on measuring the voltage--I wasn't measuring open circuit. It is slowly sinking in. To see if I understand: 1) I am seeing lower amps as my system (2P2S) is 24V instead of 12V and 2) there...

You've correctly interpreted my challenge as the rest of the wiring is under two panels and I don't have access to those unless I remove the brackets screwed into the roof. I was hoping measuring volts and amps would tell me how it is wired. Yes, I saw the corrosion as well and will be...

@cass3825, thanks for the cardboard tip. I will definitely do this next weekend assuming we have sun. @SolarRat, I measured the current at the combiner box and at the input side of the SCC. At the SCC I left the negative wire connected to the SCC and passed the positive wire through the...

Thanks @SolarRat. I've thought about another meter but this one test fine on the alternator amperage and I don't know anyone who has one I can borrow. I might try harder as I really don't want to pull up the panels. The numbers don't make sense to me, so I probably won't have a choice though.

I gave up looking for a different solution and went with the KISAE DMT-1250 B2B/MPPT and AC-1260 Smart Battery Charger as they should be close to drop-in replacements for what is there now. The batteries arrived and are now installed, and I moved the solar panel wiring (the PWM was on the...

Any solutions available other than the REDARC Manager30 for an all-in-one B2B, MPPT and AC charger? To get best performance when switching from AGM to LiFePO4, I'm looking to replace the existing charger, battery isolator and PWM SCC in my step van RV. I'm accepting the tradeoffs of opting for...

I was scratching my head on that as well. I did some googling and bailed midway as it didn't seem like a productive use of time. I was curious if the test protocols didn't really reflect how a fridge would be used and/or weren't technology agnostic. The ENERGY STAR(R) Program Requirements for...

It isn't easy to identify inverter fridges in the US via a web search or even on the product pages. Here's a good thread on the topic: https://forum.solar-electric.com/discussion/351398/lg-inverter-refrigerators The 20cuft LG LTCS20020S is $700 at Home Depot (inverter is shown at the very...
