    Six and a half years with no refrigerator ..

    Alpicools cost less. But while I could be a jerk and say what I just did, 2 years ago I was amazed compressors came in low amp 12v units AND were affordable. Was out of the loop then and caught up, like you are now. This season saw a full-size RV fridge with seperate fridge/freezer guy got for...

    Zamp solar panels

    This came back from the dead. We still sell Zamp and let's say in 2018 something came up with Zamps MAP pricing between the same product from two different sources and Zamp said one source had A cells while the other source had B cells. Nothing is indicated on a panel what 'class' the cells are...

    Curious about the chain or hookup of a system.

    Ignore the load out. If you're in a situation like I am I use load out to another controller to charge my starter battery but that's on a controller with a programmable load out and an advanced subject so for now ignore the the load out. So it goes kinda like you stated: Solar panel > regulator...

    Cheapest Easiest way to check used panels?

    There can be volts without amps. Get a dirt cheap amp clamp and just point the panel to the sun and short the panel leads together then amp clamp it to read the amps. Okay edit here: to check volts off MC4's don't poke the wire, touch the leads at the MC4 ends. For amps plug + into - MC4 (not...

    Need some help for my solar system in my campervan

    Let me simplify: My 1000w pure sign inverter uses .9 amps to power itself, 1.5a when the fan turns on. I can run a corded Dremel with it, my entire entertainment station AND charge my laptop and phone and it's not wired to the ac panel. Adapters are great for day trips, have one in my car.

    Is this a good setup for small DIY battery bank?

    Just my thought on your fridge, it's a 3 way which means it's absorption which means it's a power hog on electric so keep it on propane. Also 800w ac for tea is about 80ish amps dc. So rundown: 1. dunno. 2. Basic and Later mean you're learning and heading to v3. I'd just recommend a Battleborn...

    Need some help for my solar system in my campervan

    Nhh, 12-19v requires power from the adapter also so which is less? adapter or inverter? Have an Asus gaming laptop requires 19.5v input and a Acer NAV50 netbook just at 19V, the powerbrick sizes are for the amps not the volts- I'd take a pure sine inverter over adapter any day simply due to...

    1,000 watt vs. 1,500 watt Pure Sine Waive Inverter

    Biggest difference: battery connector arraingment. On the 1000w Tech-On (I have it) they suck! + and - dang near touching each other with no shield like that 1500w GoWISE. The Tech-on is great through, has survived 2 summers 110+ F unshaded on the doghouse of my motorhome and never quit due to...

    Need some help for my solar system in my campervan

    Just to butt in a sec and leave- the fridge is DC, figure it'll always draw just under an amp and 4-4.5a when the compressor is on- I have an Alpicool C20. For inverter size look at the power brick of the macbook (if it has one- don't know Apple stuff) to know how many watts it uses, but...

    Issues with LI battery used in a standard 12 volt system.

    Battery solenoid to the rescue.

    66 amps Wire Guage

    #6 or 8 will be fine, linked chart starts at 10 feet.

    Multiple charge controllers on a single battery 'fight' each other.

    Sorry to say but this is a real thing. I've done it with zero problems. After doing a T/S on a rig for something else found out his inverter/charger will start charging immediately plugged in but takes 2 minutes clicking on and off before charginging when the generator is on- probably a...

    66 amps Wire Guage

    Figure 72amps. Look up a DC wiring chart for amps/length. For example this thing says for a 15' run at 30' with a 3% loss use #4.

    66 amps Wire Guage

    In series only 8.85 amps would be coming down at 240ish volts so depends on the length of run 10 gauge or 8 gauge would be fine. What matters is wire size from controller to batteries in your case and that's based on again the run and system voltage.
