Hi everyone!
Looking forward to putting in my first order with Renogy, when the Eclipse 100W Rigid panels come back in stock (when will this be I wonder???).
Right now the system I am planning is 4 - 100W Eclipse panels fed into a Victron MPPT Smart Solar 100/50 Charge controller, with a the Victron 712 Battery monitor. This will feed two Renogy 200AH 12v AGMs (||). These batteries will be hooked to the Renogy 2000W Pure Sine Inverter/charger, which will have shore power input. I also eventually want to be able to charge off an alternator. I am planning on using the Sterling 60A Battery to Battery charger for this purpose, which will be hooked directly to the battery bank as well.
A couple questions for those in the know:
- Does this sound like a logical layout?
- I'm assuming I shouldn't go with anything larger than a 30A inlet for shore power with this inverter/charger setup?
- Would it make sense to go with a separate inverter and charger, to allow higher current shore power?
- Is there any reason to fuse the line in between the battery bank and the inverter/charger?
- Is there anything else I should be aware of, since I'll effectively have three separate inputs to the same battery bank (Solar, Shore and Alternator)?
Thank you in advance!

Before you buy anything....
Ask yourself what are you hoping to run off of your system? Is it going to be stationary or mobile?

Before you buy anything.... Ask yourself what are you hoping to run off of your system? Is it going to be stationary or mobile? Thank you! This will be installed in Sprinter Van, so mobile. Load includes: 2 - Maxxair fans, 130L fridge freezer, 2 - Laptops and spare monitor/TV (for working remotely), 3 - smart phones, 1 - tablet, Webasto Heater, fan for composting toilet, Vitamix blender, coffee maker (we may start using French Press more often again though), lighting, onboard air compressor, Shurflo water pump, Stereo with amplifier, and a dehumidifier for wet locals or long days out skiing. I also anticipate running an air conditioning unit up to a couple hours a day off of the battery bank, and off of shore power when available. I was considering in floor heating, but am leaning away from it right now. |

It would be real nice to be able to run all of that off of such a small system but I don't believe it will be large enough what you are considering unless you have some kind of back up..... A lot of back up....
I couldn't run all of that off of my system and it's almost 3 times larger...
Best of luck....

As previously mentioned, you need to first be sure of the system you're getting before wondering whether the electrical layout will be suiting. Since you have your known electronics, we would recommend you try our system sizer and/or get a tally of the actual (hours) daily consumption you will be using each electronic. www.renogy.com/smart-system-sizer/1. So far sounds like a logical layout 2. The inverter charger will pull what it needs from the shore power, but 30A is a good value. 3. This is your decision. The benefit to the invertercharger is that it has an integrated transfer switch that works like an inverter/charger hence the name. 2-3 component functions in one (inverter, battery charger, and transfer switch). 4. Fusing between the inverter/charger and battery protects your inverter/charger, so it is recommended. Wiring AWG is equally important! 5. You'll have to be weary about wiring and disconnects most likely. Hope this helps! -Renogy Team |

Thank you both for the replies!
I've calculated the draw of all the loads and should be good to go on that front, I'm not sure why you can't run as much. I have a friend here in town that has a similar setup with only a 300W system and seems to be pretty happy.
Thank you for the answers to my questions!

I have a friend here in town that has a similar setup with only a 300W system and seems to be pretty happy. So he's totally off grid and he can run a heater/AC and everything else? If so he is a very lucky man...
I hope your as lucky...

The heater is diesel powered, but still draws a small load. By my calculations, based on the draw of the A/C, I shouldn't have any problems running it for a couple hours a day. Here's a link to some others who have run A/C off of solar. They have about twice the amount of solar/battery, but they also have an A/C that is much, much larger as well, plus I'm not looking to run it all day. The A/C I've been looking at it a 12V unit. www.gonewiththewynns.com/off-grid-solar-rv-air-conditioning |
