    Whole roof solar replacement

    Finally getting around to upgrading my panels. I'm trying not to drill anymore holes in the roof so plan is to utilize the Girard awning brackets and the threaded rods I initially installed. I'll be mounting these Renogy 320w panels horizontal and tilted up a bit to get above all the ACs...

    SOK 48v 100ah Recommended charge voltage?

    My Victron system has been getting alerts from my SOK batteries about high voltage when the batteries are fully charged. It seems they're reporting the voltage limit as 56V so I lowered my voltage down to 55.8 in DVCC and no more errors. Problem is its reporting the charge is only 88%...

    Bussbar/circuit panel for medium sized 12v loads?

    My 12v bay was feeling neglected so started on rearranging them. Actually managed to fit 2 air compressors in saving a ton of space in another bay. I ordered a couple 200a mrbf fuses and blocks to connect the batteries to the Lynx. I'm thinking of adding that little breaker for my small...

    24v large FLA AC charger?

    Seems large 24v chargers are hard to find. My coach came with a power a 30a charger but it died (my fault, likely dropped it too many time) . I'm wanting to max out a 120v outlet so ideally something like 75amps. Anyone know of a 28.5v 60-75a charger? The plan is to have it as an emergency...

    Victron Prioritize solar over grid

    Does anyone have this enabled on a Quattro? I'm playing with it now until I can get ESS setup and feed excess solar to my house. On my system I have Shore coming into AC1 on my 48V dual Quattros then I have OUT1 from the quattros going to a panel powering half the outlets, and to my 12V...

    Solar performance results under trees

    I live in the woods in Ohio and currently no leaves. On my RV I have 18x100w panels, 3x100w in series to my 12V and 5s3p 1500w to my 48v. I'm noticing about a 20% increase in performance in the series vs parallel when under shading. On days when I'm on the road and parked usually under...

    What does the ethernet port do on the Victron energy meter

    I'm getting around to ESS and configuring my Victron RV system to offset my house's power consumption. The plan is to have 4kw solar on the RV, plus 2kw solar on a trailer and maybe more on a ground station. These will plug into the RV's MPPTs 48V system which then will use the split phase...

    Order of operations when installing for grid tied?

    I'm finally getting into building solar array for my houses and confused on the order on how to do a self install. So far I have 4 pallets of panels and a SolarEdge 10kw inverter. This will be specifically for AEP WV (Appalachian Electric Power) net metering. My sole goal is to save on...

    Make sure you put drip loops on comm cables to batteries

    Mounted my batteries with posts and everything up to make wiring easier and fit better. Found out when massive storms a couple drops can get into the hinge of my bay door or somewhere and follow the rj45 cables right into my batteries BMS. Fried one 2 weeks ago but didn't find the root cause...

    Auragen??

    Anyone have Auragen or know any info about them? Seems to be able to connect to engine to provide 120/240 AC directly regardless of RPM. I've seen a couple other coaches that have 8500w models but they have up to 20kw. This would be ideal to charge while driving Found a couple on ebay but...

    Optimal alternator setup?

    Currently I have a 24v 70a alternator set at 27v then have a 24v 270a alternator set at about 28v. The big alternator is oil cooled, industrial and weighs like 100 lbs. Well the field wire came loose on the big one so I'm replacing it and now wondering if there's a better setup. Currently...

    LFP UPS rack mount options?

    Are there any built systems that use LFP and provide UPS backup without loss of power? Any rack mountable 4u or similar size? Should I consider something like an ecoflow to use as a backup? I manage a bunch of smaller offices with a few servers and network gear. Most are under 1500w...

    Victron dual inverters split phase but on 120 dogbone

    Running Victron inverters in split phase but using this dogbone adapter going from 240v 50a to 120v 15a and it appears that it powers both legs. I know many including myself on here said we need to modify these dogbones but apparently not. https://a.co/d/imQcNmm Victrons showing both legs...

    Do Ecoflows and others stay on 24/7?

    Working to finish my cargo trailer build once it warms up. Could I plug in 1000w+ of solar into the ecoflow then use it's 12v output to a DC-DC converter and keep my trailer battery topped off, along with leaving the outlets on all the time? Say if I want to leave it running for months...

    Net metering multiple properties?

    I was told by someone that they have solar at one property which they have a 2nd house with the same utility and it offsets this property's bill. I've tried to search but haven't heard of this before. Is this normal for net metering? I'm planning an install in WV with AEP (Appalachian...

    Multiple MPPTS on same solar array?

    How exactly do MPPTs work? So I have an enclosed trailer I sometimes take behind my RV and other times its just sitting around my house. I added 1000w solar to its roof and likely will put another 600-1000 more. Inside the trailer is just a SLA 100ah battery for lights and tongue jack but...

    Blowing 50a shore power breakers

    I keep having issues with blowing breakers when at campgrounds when I set my Victron inverters to 50a. Someplaces I'm able to set to 45a and others have to be below 40a. I know NEC has a 80% rule but that's over 3 hours and usually it trips within 30 minutes. I believe Victron should limit...

    Monitoring Chassis and Generator battery voltage with Victron?

    Found out the Lynx shunt doesn't seem to have an aux voltage monitor like the smartshunt. I'm wanting to add both my generator battery and my chassis batteries to Victron's CerboGX so I can log and monitor them both but not sure what I can buy to get them added. I bought a Smart battery...

    What percent charge do you get from dc-dc from alternator?

    I have a 24v alternator so have 24-12 dc-dc converters and 24-48 dc-dc converters, all victron Orions. Seems I can't get either to charge to 100%. The 12v system is cranked all the way up but can't seem to get above 70%ish charge and it slows down the more charged the battery gets. Still...

    Generator battery voltage issues

    My 20kw genset in my RV has a dedicated battery which I replaced with a Optima D31m bluetop. I also removed a huge 240v fan in a squirrel cage and replaced it with 2x80w 12v fans. The genset seems to have a very small alternator and can't handle the load, so I added one of those htrc 20a...

    Unistrut panel mounting without gaps?

    I have a few solar projects I'm planning on starting and was planning on using unistruts/superstruts but the brackets all seem to have a couple inch gap for the screw then just clamp the panels down which doesn't seem ideal. Is there some mounts that'll secure from the bottom of the panel and...

    Panels above voc?

    I have 18 of these renogy 100w panels in 6s3p. Voc is 24.3 each so 145.8v should be the max right? Hooked up to my 150/100 Victron mppt and today got multiple high voltage errors when driving and solar was odd since battery was full. It was during heavy rain with complete cloud coverage...
