scrubjaysnest trial and error method of RV solar installs

[scrubjaysnest]

Started messing with solar in 2012.
1st RV install was a solar kit of 2 80 watt panels and Sunsaver 10. 1st error was made when I added a second 105aH deep cycle. ooops not enough solar and the PWM controller was too small.
updated to this. 2 80 watt panels moved to the roof with tilting system and add 2 100 watt panes as portable. Also added TS-45 PWM for CC. Since the batteries were at the very back of the trailer, wiring was up graded to 8 AWG from the tow vehicle in parallel with existing 10 AWG.

Another mistake was using Square D QO breakers. While the are rated for 48 VDC the AIC isn't high enough which resulted in changing to Midnight Solar.
lessons learned DO AN Energy Audit even though it's a pita. Use bigger wire and pay attention to fuse and breaker voltage ratings. Also AIC.

In 2016 robbed everything from the trailer except the 2 80 watt panels and put the sunsaver 10 back in. Moved everything to the current motorhome and redid the energy audit. Inspected the factory installed breakers, left them alone. Bought 3 more 100 watt panels. in 2017 put 2 on the roof using the same tilt system design from the trailer and completed stands to have 3 portables
Mounted 400 watt inverter we were using to charge the laptops. Added Progressive Dynamics 45 amp converter which lets me charge batts from shore power at 14.4 volts.
The shunt for the Trimetric is mounted to the frame under the entrance steps since that is where Thor put the batteries (so they get all the highway crud thrown on them).

2000 watt 12 volt inverter arrives next week. Ordered the Expert Power after the success of the 3000 watt version this past year. 9 per cent off.
These look like Aims-Sigineer-Sungold for much less.
Those will require almost total rewire of house batteries and breakers.

Started upgrades on the MH solar. Installed a 100/20 and 100/30 after removing the Morningstar TS 45 pwm. At the moment the 2- 100 watt roof panels feed the 100/20 in parallel. All wiring there is 10 AWG.
8 AWG from the portable port was kept to the input breaker. 6 AWG from there to the 100/30. Kept the 50 amp breaker for the 100/30 to the battery tie point. Kept the 15 amp breaker from the roof panels and the 20 amp breaker from the portable panel port. Added a 30 amp for the 100/20 output to the battery tie point.

Big job still ahead is rewiring the battery bank to add the 2000 watt inverter.
