Portable Solar Powered Battery Backup

I decided to build a battery box that is powered by solar I can use for emerergency power backup and camping or whatever else where it's useful.
This stemmed from some foldable solar panels I got for a very good deal, I wanted to put them to work.

MATERIALS
Battery box
12.8 V 100AH LFP batteries x2
Husky rolling connect 3 piece toolbox
24V to 12V 30A buck converter
12V car socket
12v to 5v PD charging adapter
20A DC circuit Breaker
6A 2 pole DC circuit Breaker
150A battery cutoff/disconnect
2 awg wire
10 awg wire
12 awg wire

Inverter box
2000W Pure Sine Inverter
40 or 60A MPPT solar charge controller
100A shunt
50A 2 pole DC circuit breaker (for solar input)
125A DC circuit breaker (main power cutoff
60A DC circuit breaker (cutoff for BV to MPPT)
20A 2 pole AC circuit breaker (ac power out to load)
DC distribution busses
24v thermostat relay
24v 8025 fan
Weather rated nema 5-15 surface mount plugs
Solar connectors
125A Anderson PowerPole connectors
10-30v led lights
Stainless steel machine screws for mounting (FHCS and SHCS)
2 Awg wire
12 awg wire
24 awg wire

Other items
I used the top box of the toolbox as storage for my 36v 5amp AC charger
Solar extension cables
Powerpole to solar plug adapters (home made)
Solar splitter cables

Circuit
NOTE: I did not ground bond the ground, it's currently floating as I'm waiting to consult an electrician on best grounding procedures for this application of a split phase output of AC current.

Functional testing - everything worked perfectly
Home made adapter cables for solar panels
Just finishing up wiring, had to order a 2 pole breaker because I didn't realize that the output on the Inverter is split phase so for safety I did a 2 pole breaker. Below is the new breaker.

I added a voltage readout so I can glance and know how mucb power I have left based on voltage. Below it are the 2 12v devices for USB charging or 12v adapter as necessary for a thermoelectric cooler or other devices.
I built the battery box to be able to run and be usable if I only need DC power, it also can be turned off and then flipped into balancing mode with the other 2 pole circuit breaker

Raspberry Pi as VPN Server

Image
  Purpose The goal of this project is to build a VPN using a Raspberry Pi 3+ as the VPN server to securely and remotely establish a tunnel to access a device on the other network. Specifically to access Octopi (3d printer controller which can only be accessed locally) and control temperatures, move axes, and watch a live video feed of the nozzle or tool. Materials All materials were items I already owned or was given. I had purchased most of the following on amazon or ebay at some point in the years leading up to this. Links to parts I have purchased are below. ·        2x Raspberry Pi 3 (B +) ·        2x >= 8gb micro SD cards for raspberry pi ·        1m Endoscope camera ·        HDMI capable monitor ·        Ethernet Cable ·        USB A to USB mini (or compatible to printer...

Batch Mixing PLC System

Image
Purpose Due to a noticeable waste of product and a need to make the filling into a 1 operator job instead of 3, I pitched the idea to build a  Constraints Budget: $1000.00 Time Frame: 3 months Materials 2 large boxes C0-00DD1-D Koyo CLICK PLC C0-00AC Power Supply PSB24-060-P 24V Rhino Power supply 10 x 24V indicator lights Red, Green, Beep, light tower. 14 AWG THHN Stranded Wire White, blue stripe White Blue Red Black Green, yellow stripe Grounded conduit & connectors Terminal Blocks 2 x 80mm fans 2 x 24V thermostats 10 x DC/AC Relays Analysis Due to a very limited budget I had to make many sacrifices to keep cost low rather than industry standard. Additionally I had to take over the project from someone who already ordered some parts which came from the budget so I had to go with those parts as much as possible. Once the system was completed and debugged, the owner was very impressed at how well it performed and allocated more funds to be able to expand the system. The ne...
