Hi, I am looking to upgrade a 2013 travel trailer to a full solar / lithium configuration for boondocking and remote travel

2 questions

  1. What 12v DC to 120V AC - 3000watt Victron inverter would i need - can’t see to determine a model number ( found the Renogy 3000W P2 as an example)
  2. Based on the attached drawing, where would I connect the 3 solar panels connected to the Victron 100/50 controller with Blue Tooth

Thanks Jeff

Get yourself a Victron Multiplus 12V 3000VA. Either the Multiplus, Multiplus II if you have 30 amp service or the Multiplus 2X120 if you have 50 amp service. All three come in a 12V 3000VA model. Save yourself the trouble and avoid the Renogy.

As far as the question about the solar panels, I don’t understand what you mean. The solar panels will connect to the PV input side of the MPPT and the batteries will connect to the battery side. Is that what you are asking?

You diagram is pretty far off from correct. The Multiplus will be your inverter, charger and transfer switch. Its AC side will wire directly into your house service. This will eliminate the need for your converter and you wont need the Victron BlueSmart IP22.

Also, PLEASE don’t buy cheap Amazon batteries. I know its tempting, many people do it with seemingly good results but its unpredictable.

If you want to do this right, I recommend getting some guidance from Explorist.life. For 9.99 you can get a fully comprehensive wiring diagram along with parts lists and tutorials on how to install it. SOLAR WIRING DIAGRAMS - EXPLORIST.life

Also, read the Victron Wiring Unlimited PDF. Wiring Unlimited - Victron Energy

There’s no need to struggle through this and make unnecessary mistakes. There are tons of good resources out there.

At 3000W for the inverter power, I would also look at a 24V installation rather than 12.
The inverter and wiring will be cheaper and more efficient. A 12/24V dc/dc converter will happily look after charging from a 12V source.
