Chad Heiser Posted March 1 Report Share Posted March 1 I was going over some of my old posts and realized I said I would post some information about the new system (as of June 2022) in my new rig. I posted a brief synopsis of it here back in June 2022 after the West Coast Rally, but never followed up with any more information. We just spent a month down in Quartzsite from the end of January to the end of February boondocking the whole time with other HDTers and friends. I am very happy with the new rig and the new system. The new rig is much better for boondocking than our last one for two main reasons. The first reason is we are back to a standard RV toilet instead of the macerator toilet we had in the last rig. This means we use a lot less water when flushing the toilet. This lets us go much longer before having to empty the black tank. We only had to empty it twice in the month we were in Q and it wasn't completely full either time. We were lucky to get 10 days out of the black tank in the last rig with the macerator toilet. The second reason is my latest "system". I couldn't be happier with the new system. Like I said, we just spent a month boondocking. We lived like we were plugged in the whole time. We didn't take any special measures to conserve power, other than turning the big inverters off when we went to bed. (I have a small inverter dedicated to the residential refrigerator that stays on 24/7 to always keep the refrigerator running.) We had multiple days of cloudy and cold weather, so we ran the forced air furnace quite a bit and my wife used her seat heater in the theater seating quite a bit. We watched TV, used the microwave, Instapot, coffee pot, my wife's hair dryer and curling iron, etc. I had Starlink satellite internet running whenever the big inverters were on. We also had the normal 12 volt loads from lights and other stuff. I never drew the batteries down below 50% state of charge and we were back to 100% state of charge every afternoon (with the exception of a couple of full cloud cover days). I ran the on board generator once the entire trip. This was at the end of the trip a couple days before we left. I didn't need to run the generator, but decided to exercise it for an hour because it had been over a month since I ran it the last time. My generator only has a total of approximately 7 hours on it, which is almost all just running it to exercise it since we bought the rig in May 2022. Here is a diagram of the system in my rig: The system has more power than we (or most people) really need. I can run anything (and everything) in my rig whether it is plugged in or not. I have literally turned everything on at once and run it all from battery power (three AC's, fireplace, microwave, entertainment center, lights, etc.) with no issues. Of course I can't do this for long periods. I am obviously limited by how much solar production is occurring and how much battery capacity I have. The system has 1080 amp hours of lithium batteries, two 5KVA Victron Quattro inverter chargers (one on each leg of the 50 amp RV power panel and programmed to run in 120/240 volt split phase), one 1.2KVA Victron Phoenix inverter (dedicated to the residential refrigerator and the outlets in the bedroom slide), 3390 watts of solar, three Victron MPPT solar charge controllers (capable of a total of 225 amps of DC production at full output), a 1000 amp Victron Smartshunt (monitoring the battery bank), a 500 amp Victron SmartShunt (monitoring general 12 volt loads), two Victron Lynx Distributors supplying power and circuit protection to the system and a Lynx Power In where each battery is connected individually to the system. I also have a Victron Autotransformer installed after the on board Onan 5500 watt gas generator. This takes the 120 volt generator output and transforms it to 120/240 volt power to feed directly to the second inputs on the Quattro inverters. This negated the need for the onboard automatic transfer switch because the Quattros have built in transfer switches to switch between two power inputs (typically shore and generator). Rather than remove the ATS, I added a second shore power connection to the front of the trailer and wired it to the ATS where the generator used to connect. This gives me more options for plugging the trailer in when I need to. I also have a Victron Cerbo GX communication device with a seven inch touch screen display. The Cerbo communicates with all the Victron equipment and the internet. I added an Atkinson Electronics GSCM mini generator start control module. This device interacts with the Cerbo and allows the Cerbo to fully control the on board generator and auto start it based on a number of triggers and parameters that I can set up. The Cerbo GX adds all kinds of functionality and data logging to the system. I can literally control or program any component or function from anywhere (as long as I have internet and the trailer has internet). I can turn the inverters or generator on/off remotely, set the AC Input Current Limit, see the solar production information, battery state of charge, etc. In addition to this standard functionality, the Cerbo also allows integration of other systems. My rig came with Sea Level tank gauges. It is a newer version of the Sea Level gauges that communicates over RV-C protocol. I was able to integrate the RV-C output of the Sea Level gauges into the Cerbo so I can see all my tank levels on the Cerbo display or remotely through the internet. Victron also recently added Bluetooth sensor monitoring through the Cerbo. Specifically Mopeka LPG and Water tank Bluetooth sensors and Ruuvi Bluetooth temperature sensors. I added Mopeka sensors to my LPG tanks and the two gasoline tanks (generator and toy tanks) in the trailer. This allows me to see the levels in those tanks right next to the Sea Level tank levels on the Cerbo. I also have six Ruuvi temperature sensors mounted in my rig. I have them in the bedroom, living room, garage, inverter compartment, at the pin box outside and in the refrigerator. I can now monitor temperatures at all of those locations remotely through the Cerbo. Here is what the tanks display looks like on the Cerbo: Here is another screen showing the tank information as well as other information about the system: Here is the main Cerbo display showing the flow of energy in the system: Here is the basic VRM Dashboard that you see when you log into the system through the internet: Finally, here is the control panel through the VRM Portal that allows you to directly control items in the rig from anywhere: There is a lot more available through VRM, but these are the basics. Finally, here is a link to pictures of my system as I was installing it and other information about the system on my website. Quote Link to comment Share on other sites More sharing options...
