That is such a gorgeous setup! Beautifully laid out. I briefly considered 24v DC. Sure would be nice from an install standpoint. But I'm set up to run most of my stuff off of 12v DC. The power lost from converting 24v to 12v didn't make sense for me. Already have the inversion tax for AC. I...

How frustrating - seems like a pretty basic thing for them to have proper settings for.

I agree! I'd love to get that setup with my onboard propane tank. I'm using the Ruuvis with my RPi and they're great. They're reporting as °F for me, wonder why they're stuck in °C for you. I assume so, because it currently integrates with my Smartshunt in my travel trailer's power system. If...

Thank you! I agree about the Smartshunt, but I was hoping to benefit from two things by getting the BMV712: the relay, and the better bluetooth signal. Smartshunt has less reliable BT signal compared to BMV 712 since the latter has the BT antenna in the display rather than directly on the shunt...

Thank you very much Jim! Appreciate the feedback and clarifications. I've updated the diagram accordingly. I'm definitely curious about the Cerbo GX. I've been using the RaspberryPi running Victron's Venus OS on my previous system and that's been good, but will looking closely at switching to a...

Hello there. I'm upgrading to a larger full time class-c RV from my little Starcraft TT, and so it's time to build a new, bigger solar power system. This is my first initial draft of what I have in mind. Still need to measure length of all the wire runs to determine wire gauges. But in the mean...

Thank you very much. Just trying to be respectful of other people's time! The renogy inverter/charger settings are weird (manual attached). Current config is: Float Voltage: 13.8 Max Charge Voltage: 14.4 My victron Smart Shunt BMS settings are also attached. The built-in Renogy LiFePO4 BMS is...

Check out this video of what's happening while I'm plugged into 30A shore power at a campsite: https://www.dropbox.com/s/r4ynkuemdo01ce7/fluctuation.mov?dl=0 Full system specs and diagram attached. SCC & SmartBMS Shunt settings attached too. Here's a link to the real-time VRM dashboard...

Thank you all for helping me sort this out. I believe my initial concern has been addressed. Telling the Inverter/Charger to treat the batteries as a custom configuration with float voltage specified, and recalibrating my smart shunt is now keepings the battery bank charged while connected to...

You were absolutely right.

Thank you! Made the update.

Here's the latest configuration based on folks' recommendations here: Power Sources: Shore Power (30A): Plugged in Solar Array (740W): Enabled (but sun is setting now) Renogy Inverter Charger: Config Profile: Manual Battery Type: Non-LiFePO4 (This is the only way it will allow me to set a...

Oh that’s interesting. I just tried unplugged and put a lite load on the inverter, and the array never jumped in to supply power. That’s not what normally happens for me.

This is how the smart shunt is configured:

That makes sense. The SCC is seeing 13.9. The shunt is showing a voltage of ~13.9 at 86% charge. Here’s a link to my victron VRM dashboard with real-time data: https://vrm.victronenergy.com/installation/129513/share/6b2bbe34 And here’s what both of SCCs’ parameters are configured as:

Thank you very much for adding your experience here. Looks like a number of you are configuring a float voltage for your LiFePO4 batteries, so I will try that today. After some of the previous suggestions, I did the manual configuration for LiFePO4 batteries on my inverter/charger and set the...

I'll give it a shot! Thank you.

So I think you're saying that even when on shore power, your batteries are being depleted? That's pretty much the core of my question.

That's cumulative drain, not just in one night. I'm not concerned about the energy consumption because that is circumstantial: I'm temporarily in a region that is getting almost no usable sunlight, it's below freezing even in the middle of the day so I'm my using my camper's furnace 24/7, and...

I noticed that if I briefly switch the battery disconnect to “off” and then back to “on” the inverter charger kicks in and charged my batteries back to 100%. But after that, the same thing happens all over again. It lets my 12v circuit discharge the batteries.

I’ve noticed that if I turn off the battery dis thats the one!

The manual provides few details. This is all it says: LiFePo profile will stop charging at 14.7v. Charging will resume at 12.5v.

I have it set to use the default LiFePo charging profile, which prevents customization of certain settings like Float profile/voltage. I'll try manually configuring it and see what happens.

I have the Renogy 2000Watt Inverter Charger and it's my first time using an inverter charger. I'm confused by its behavior, but maybe this is normal: When I plug into shore power, my batteries are charged to 100% by the inverter charger, but then after reaching 100% charge, the inverter charger...

Thank you 2x! Congrats on the new tiny camper! Very similar to my AR-One 14RB! Where will you take it first?

Fair question. It's certainly not something I'd normally be doing. I wanted to see if it was possible to keep the AC circuits powered while the DC circuit was disabled. Hahaha, yeah on paper it sure looks like a lot! It's all pretty discreetly integrated though. The only place where it may seem...

Hi there. I've just about completed my first ever solar/power system build out (diagram below) after much studying and learning from folks here. I have a question about using my inverter charger with shore power while disconnected from my battery bank. Today I had the following conditions...

The victron will know when it's fully charged without me having to do anything?

Will my batteries know when to stop charging themselves? Do the solar charge controllers and inverter charger need to know the present state of charge? Forgive my naïveté ?

Hey there. I just hooked up a new system with two 170ah lifepo4 batteries (12v) with the Victron SmartShunt. The SmartShunt wants me to tell it the state of charge of the two batteries. How do I determine the SOC? Is it really just a matter of looking at the battery voltage the smartshunt...

Hey that's a great tip, thank you. I'll put the charger in the camper instead of the tow vehicle to minimize the drop from charger to battery. And I've decided to go with Victron 12/12-30amp instead of the Renogy. The more familiar I've become with how these electrical systems work, the more...

Good! Glad to hear it. It's been a pleasure working with you on this too! I've learned a lot. Thank you so much for your patience and generosity. Round trip journey should be approx 30-40ft. Okay, this feels like a final-ish diagram especially now that it has your blessing. I still have some...

Thank you! Fixed that one in the latest diagram above. Is that the only ground I need to run for that system since everything is connected to the lynx (or busbar if I go that route).

Got clarity on the tow cable wiring and how it powers the systems over there. Wiring diagram 4.1 attached.

Tow cable gets its power directly from the tow vehicle's power system. Works without the DC-to-DC battery charger. I would run a separate wire for DC-to-DC charger from tow vehicle to camper. And I might get a higher camp DC-to-DC battery charger if I modify my tow vehicle to idle at a higher...
