Why are batteries always stated as Amps while solar panels are watts? In this case I could see 12v but otherwise I'd be guessing 12, 24, 48v which has a huge difference in capacity.
@vladimus9749 In most cases they are labeled with voltage, amp hour capacity, and also watt hours. Solar panels don't have a "capacity" so I'm not sure how else you would want them to label the "power" production rating of the panel...
Great video! Where are you guys located and what’s your website? I’m interested in hiring you in the future.
We are located in Buckeye, AZ and we can be found on social media outlets by our name: RV Solar Concepts. Website is www.RvSolarConcepts.com
One question, why no go 24 volts?
Good Question!
We usually reserve 24V systems for builds that will have multiple inverters. Victron recommends 4/0 wiring for each 3000VA inverter fused at 400 amps at 12V. This becomes problematic when you have more than one inverter at 12V you have to start sourcing very high amperage shunts, bus bars, etc... and also requires more runs of very large gauge wire. In those cases we will opt for 24V battery bank operation.
The customers that owned this rig are living in it full time but their power usage only warranted 1 inverter so we stayed at 12V. The pros and cons of 12V vs 24V were discussed with the customer prior to the build and they decided they did not like the idea of having a buck converter (24V to 12V converter) as a single point of failure for all of their 12V appliances, hydraulic leveling system, lighting, water pump, etc...
Going to a 24V battery bank would have saved some money on the build by allowing us to use smaller wire and one solar controller instead of two, but they wanted the redundancy in case of any future issues.
what does a system like this cost?
I believe this one was around $16k all said and done.
