Solar upgrade

A couple months ago I completed my solar upgrade. We have used it several times and everything seems to be working well. We went from 400W of solar to 1720W. Upgraded the batteries from 300AH to 920AH. Equipment installed includes:
  • Victron Quatro II 3000W
  • Victron Cerbo GX
  • Victron VE.Bus Smart Dongle
  • Victron GX Touch 70
  • Victron BMV 712 & shunt
  • Twin Victron MPPT 150/60-Tr charge controllers
  • Twin Victron Orion-Tr Smart 12/12-30 DC-DC Chargers
  • Victron MK3-USB interface
  • Twin Epoch 460AH smart heated batteries
  • Eight 215W solar panels
  • Two Micro-Air Easy Starts

Moved the Hughes Autoformer and Power Watchdog to the area behind the wall where the OEM transfer switch was.

We now have four ways to charge the batteries: Shore power, generator, solar, truck.

While I was on the roof, I also permanently mounted the Starlink antenna; mounted the router and power supply in the basement overhead.

That is some awesome work, gets my seal of approval.

I really appreciate the heat shrink over the crimp lugs and extending back over the insulation. The weakest point of a termination is at the end of the lug/ end of insulation. This eases the stress at that point. You even color coded them for the polarity.

Awesome work! That gets my seal of approval.

I really appreciate the heat shrink over the crimp lugs extending back on the wire insulation a little. The weakest point of any termination is at the end of the lug barrel and insulation cut back. This practice relieves a lot of stress at that point. You even color coded the heat shrink for polarity.

It's not shown in the photos, but I also used heavy duty heat shrink on the MC4 connectors on the roof for better weatherproofing.

For those wondering how much stuff you can cram into the area under the stairs......

I had to relocate the washer drain to do it. And, in case you are wondering why I did not use hardwired Hughes equipment; that would have been preferred, but I already owned this stuff.

Very nice set up Scott. Quality workmanship and equipment. Should make Quartzsite and all your other boondocking much more comfortable with less work. Job well done!

Nice / clean install!

Does the Quattro power share like the Multiplus ii?

I am looking at something like you have done, but I want to go 48V so I think I would beed a Quattro, correct? (50 A shore power)

The main difference is the Quatro has a second AC input for a generator; functions as a transfer switch.

By using the Quattor, I eliminated three other boxes; charger, transfer switch, inverter and freed up some space.

Scott,

You sure get a lot more utility out of the hybrid inverter/chargers than keeping the standard inverter and converter that come on the rigs,
