  1. Now a Honda CRV, but previously Honda Fit and several different year Geo Trackers. Trackers and Fit were my favorites, because they only weighed about 2600 lbs, didn't even slow me down.
  2. Actually because these are reconfigured EV batteries, no recommendations from manufacturer. I also have the 14s battery and run absorb/bulk at 57.2 and float at 57. I would not get a charge controller or inverter charger that you could not set individual charge voltages. The Magnum has a lithium setting, but is a constant current, constant voltage type, that only charges at 55 volts. But it also has a custom setting that allows you to set your voltages higher. My solar controllers also have the ability to set voltages. Many grid tie inverters accept 600 volts from a string of panels in series. Think this may be the legal limit on residential systems, so I feel pretty safe running 240 volts into my 250 volt solar controllers. .
  3. Good to know, have the Victron controllers and inverter in the coach, the bluetooth feature is great.
  4. Don't know if there is any difference in performance between the two. I went the high voltage route because my panels are on the roof of my S&B, so a long run of wire was necessary. I bought two Midnite Solar 250 volt charge controllers for $350 ea, for redundancy, and in case I wanted to expand in the future.
  5. It will depend on the panels and wiring. the PT-100 will accept up to 248 volt input, while the Victron, 150 volts. Running 96 cell panels will give you 60 volts per panel, 72 cell will be about 48 volts. So running series/parallel is your best bet to avoid a lot of heavy gauge wires. I am running two 2600 watt strings in series parallel at 240 volts, so can get by with 8 gauge from each string. Lower voltages will require bigger wire.
  6. Doubt you will ever get 4000 watts, but 4000 watts at 48 volts is only 83 amps. So your controller must handle that at what ever your input voltage is.. The midnite solar 250 will only handle 250 volts at 63 amps so I had to go with two.
  7. I am using the Sunpower 327 watt panels also, easier to fit on an RV, and higher voltage means smaller wiring. They are 20% efficiency so better than many others.
  8. As John said, to get full performance out of you lithium battery, your charging profile might have to change. Battle Born has posted a list of chargers that can be adjusted for use with their batteries. https://battlebornbatteries.com/charger-compatibility-table/
  9. The guy I buy my solar equipment from, has 65 THOUSAND watts on his roof and arrays in his yard. He is grid tied, but his electric supplier will not buy his power, he only gets credits. But he does have rental properties and he can apply the credits to them.
  10. 5 db for me too. But pretty expensive for a piece of plastic. But worth it.
  11. https://www.ebay.com/itm/10pcs-Solar-Panels-SunPower-327-Watts-High-Efficiency-Mono-Panels-327W/283633517947?epid=27022588460&hash=item4209e0057b:g:6ToAAOSw4xJdl6~B $130 for a 327 watt high efficiency [20 %] delivered to your house. Back in the day, remember paying almost $2 a watt.
  12. Thanks, just read the fine print. Not such a great deal if you stlll have to keep two LA batteries.
  13. Anyone using one of these to replace your starting batteries? https://www.raneystruckparts.com/maxwell-12-volt-heavy-duty-engine-start-module-ultracapacitor-ultra-31-1800/?gclid=Cj0KCQiAgKzwBRCjARIsABBbFug-3_jZ4Ecsfh_wkoaeXyEe0YYXZuvWfsslPKJY-NpEYYJRZwVA9TMaAmA_EALw_wcB
