not exactly a box, this is what I am designing. Not finished refining.

Appears to be our bms.

Vitron has modbus as long as use a GX device. table here

For remote monitoring I am hoping to use something like this. I am in a wheelchair and will never be in front of the working battery so I will need a remote access. Unfortunately I am a long way away from this build. https://www.waveshare.com/wiki/RS232/485_TO_ETH

nothing yet. I would think that would come before delivery.

Shipping, yes. just received today. I will be adding details to the video as I collect them.

This is interesting, and I don't have a solution for everyone. butttt... I plan on using the CAN protocol with my home automation [Home Assistant ] to monitor the batteries and modbus protocol to do monitoring and control of my Victron Multiplus. I already have the modbus connection working such...

I am thinking of fiberglass board on standoffs with cutouts to look like front of ess items from seplos. https://www.eplastics.com/fiberglass/sheets/g10-fr4-epoxy/custitem17/0.125 I am also looking at server racks.

Just ordered 8s 24v 200Amp version for a series of batteries I am building. Thanks for blazing the path here guys. I am working with a Victron MultiPlus. look forward to my build.

Haha, it's not as exciting.

Thanks a bunch for your help. Can't wait for the first real power outage.

Thanks to the help of many on this forum I have a somewhat sophisticated backup system for a portion of my house. Watch the movie for more.

Generator is "young" but I get your points. I have Stabil in everything now. Haven't had a chance yet but, Wawa gas stations have ethanol free pumps. if I was not paralyzed I would jump on the Propane option. the list of things I have for my son is too long right now. will keep you in mind...

Fridge and heat over two days. Watts out of inverter.

Fridge and heat connected.

Generator connection and case grounds

It is getting real.

yes, mine does not.

The fridge came in at less than I estimated. 1.2 kwh/day. Anyone have a good recommendation for manual transfer switch? I think this is a better diagram.

Agreed, I may not need generator. our worst outage was 6 days many years ago. So generator is mostly for extended outages. In the winter 1000watts will run heat with generator outside this system intermittently.. I am double checking fridge with Kill-a-watt. Number includes fridge, two vents...

More, can I tie all three neutral wires [grid(earth),generator, and inverter] together at the selector switch? Any advice for where to get selector switch?

re-reviewed audit. I am going to get a 2nd set of data from the fridge with killawatt. Looking good... I think. Where do I power Venus GX from? Battery? Minimum System size calculations Full Load Wattage 965 Watts Full Load W-hrs. 2167.42717 W-Hrs. Inverter efficiency 94% %...

Cleaned up diagram. 1. Do I really need a fuse on the battery? Battery has bms and a circuit breaker.

Yes, and I could even automate through Home assistant. The tiny one I bought was super cheap and a knee jerk reaction to Isaias. Better than a 400Watt inverter on a tractor ? good thing my kids were home

Need to answer a few items. 1. I can't afford solar at this time. If I get another job I will do a system for the whole house with tesla power wall or the like. 2. I did do the audit for a larger subset before the layoffs killed that plan. Used Sense device. Need to reduce to smaller subset...

Newbie here, but I am an engineer so.... ?:poop: Anyway I have ALS and I require a vent , and therefore electricity, to breathe. I have been avoiding the emergency backup question for too long. Isaias was scary, 17 hours without power. I won't go into the BS I had my wife do to keep me alive...

so glad I have real data. more devices to be found.

I am geeking out. I use a machine to help me cough. From the power output I can see how many times I coughed.

Measuring.....

It is defined. Measure phase in progress.

Interesting, let's see I only have three resistance devices in the house. washer, dryer, and dishwasher. for my purpose this sounds like it would work well.

anyone using this? https://sense.com/

Never tease a data geek with a tool like that....

I have kilawatt,. my not so willing assistant just went back to college,. I need real data from well pump.

Understood, and how do others measure this duration,?
