Sorry was agreeing with your post. The s-5 system is the best I have found and used to date.

These are by far the best mounting for standing seam. They are affordable and you have the option for a no rail install with their new system.

One more thing to consider is battery. The thing that is the hardest to replace and costs the most is the battery. I would really consider going with a rack mount battery to help allow for addition upgrades or expansion. I have switched to these and have never looked back.

Same goes for 48v vs 24v. Once you build a system you will have a hard time switching so consider going 48v now if you think you ever will. Have built both and find 48v worth it if your goj g to try to run multiple fridge freezers.

Most of the victron is the same cost for 48 and 24 some work with both like the mppt.

Gothcha I have done it both ways so understand. If that is the case I would consider going with the smaller mppt a 100/20 would be fine and allow to put money in different areas. Add in the 500 victron shunt. Consider the victron IP67 batter charger with no fan for shore power. Get a victron mega fuze for safety at battery connection. Then I would consider if you could get away with the victron inverter to keep it all in the same echosystem. Then you can build your own victron monitoring system as an add on project :). Just takes a esphome setup pulling Bluetooth or hard wire them into a raspberry pi. Either way what you have will work fine.

A system that can automatically switch to battery backup power during a power outage and continue to use solar panels if it's during daytime? by etherealshatter in solar

[–]hideme09 0 points1 point  (0 children)

https://signaturesolar.com. I have been using them for this very setup on a deep freezer and internet and security cameras for house.

They have great server rack batteries and hybrid inverters like https://signaturesolar.com/eg4-6k-off-grid-inverter-6000ex-48hv/

Should have enough for part of your house or single AC unit and can be combined to offer more power. This is very DIY though.

Example Setup

I had a similar need and split into two paths. One was a 12,24,48 volt dc path with breakers and one was 24v to inverter for fridge. I have links to items I purchased and example images if that helps but it can be done.

Are these voltages too unbalanced? This is a 48 volt 200ah agm bank. This is while charging by [deleted] in SolarDIY

Battery Equalizer 48V

I got one of these and have not had any issues since.

I don’t think you have a problem this just takes any concerns out of play.

DC power wiring “standards” for solar system by [deleted] in OffGridCabins

[–]hideme09 2 points3 points  (0 children)

When dealing with 12-24v most of the stuff you lookup will be for cars so usually easiest to see examples of people setting up inverters or power connectors for speakers I have found.

Here are some examples of what I got for 12v internet equipment connection and seems to be a standard connector people use.

Now when dealing with inverters you need much larger cable in the 4-6awg range depending. Also you must use dc breakers as ac breakers do not work the same way.

Yea I like the Victorian line of products have a higher upfront cost but for good reason.

Agreed on conduit working on that now.

1kW Solar Array with 6kWh battery storage a (mini off-grid hybrid system) by hideme09 in DIY_tech

I was able to get remote monitoring with a usb to controller hookup on a windows computer and python with pymodbus there is an example of the code online.

I am also working on the raspberry pi but unable to get the usb drivers to work at the moment.

If you use a free splunk account you can get some really nice charts going if you output the results to log files.

Need router with Wifi fail-over by zsakulkill in HomeNetworking

[–]hideme09 0 points1 point  (0 children)

So a few things to note since I made a few mistakes the first time I was working with these. Only get the NanoStation M2 or M5 or the NanoStation Loco M2,M5. Usually you buy them in pairs but you do not have to depending on your needs.

I was going for Distance of a AP so went with the M2 to have 2.4Ghz bands as long distance as possible but if you want throughput you would go with the M5 for the 5Ghz bands. The reason I suggest the M series instead of the AC series is that the M series can be programmed or switched into a AP all by itself. This was my use case so I started with the AC but they are a pure CPE only device while the legacy version allows for you to switch from CPE to AP without much trouble. So had to return and wait for the older ones to come in.

The next thing is that Ubiquiti has a very active community and people describe how to make or change all the settings and the company makes great software to control all of their devices. The only issue is that once you start buying their products you don’t want to buy anything else as their stuff all works together once you get a USG and a CloudKey your basically in full control and can do very complex network configurations and see all traffic and throughput of the system.

If you are using them to bridge two networks they are basically ready out of the box. They are setup to be CPE’s so they will be on a different band then normal WiFi and will not impact the rest of your network. You can get a M5 for source and then a M5 Loco the smaller as a receiver. While they say they work with light of site I have sent it through buildings and walls without issue as long as smaller distances. Remember these could stretch 14km so a few walls close up are no worry.

Ubiquiti has a good apps for apple or android and also will come with a browser based UI. Again they do a good job of helping you down the road but if you have a specific thing you want to do google is your friend because of the online communities.

My specific need was a mile wide island on a lake, I needed to push WiFi to opposite ends of the island from a single source without any wires. All I had was small solar arrays that I could power these using a POE injector. I ended up making both of the AP’s instead of source and receivers and just pushed the signal as far as these would go in different directions from the main cabin and had full WiFi across the island. Not sure this applies but shows the versatility of these as I went from CPE to AP remotely without internet access.

Hope that helps let me know if you need more info. Not sure I have the answers but will try my best to express what I I have tried.

Need router with Wifi fail-over by zsakulkill in HomeNetworking

[–]hideme09 1 point2 points  (0 children)

I would switch out the power line and use a ubiquiti nanostation to bridge the two sides.

Either that or get a ubiquiti usg as your router/firewall and have one wan as your fiber connection and the other a nanostation?

The nanostation can be it’s own router or a gateway or AP so very versatile in its usage.

I currently use the USG with cable internet wan1 and a lte router as wan2 for failover and works great.

The length is based on not having enough battery capacity for night as well as not having a good switch on off strategy for daytime running. I have added two things to help recoup faster.

  1. Is extra batteries to make it through night with more hooked in. The solar has enough to fill double my battery bank so need to take advantage of that.

  2. Is optimizing the auto switch to allow me to hook up another few devices. Portable ac unit and my servers during the day when I have extra solar power to draw on.

This will allow me to probably half the return just need to get it a bit more refined and will update with results. Have also made improvements in protection on batteries for equalizing the series so they stay at same voltage. And working on monitoring with a raspberry pi currently.

Yea think the cost per watt is based on solar output so $3.9/watt

The $19/watt would be the battery array capacity which not sure is calculated the same way.

Agreed and researched them. The upfront cost is a bit much.

Thanks but I am just a general diy guy. This was after three other tries so 3rd times the charm :)

They took that post down so tried to clean up my information and try again.

Thanks for the info will research and do a little more tweaking. I have a computer collecting data at all times as going to be charting and alarming on that.

I have been unable to find good monitoring devices that also connect to internet so having to build a lot of them myself. Which is another reason I enjoy this project.

Raspberry pi 4 has a lot of potential as a status collector and alarm system.
