Hopefully someone will find something useful. I jumped off the Will Prowse (thanks Will) springboard and this is my completed backup solar system. Here is a few specifics:
1. LV5048 5KW 240V split phase inverter. 72watt idle power
2. 8 battleborn batteries in this aluminum C&D (cheap and dirty...
Haha thanks for edumacation....I learned something as a electrician hacker....get plenty plenty plenty of all of the varieties of else....cause things can change in design. Got els at homely despot
Yes I am doing 120/120 split phase....(240). I didn't do the cheaper sinopoly because I liked the idea of having to not deal with lots of BMS wires. Yes you could make sure it was all done right with strain relief on the leads and providing a proper enclosure...like battleborn has!. The...
My system leaves a lot for expansion. Your system likely uses less idle power and is far less expensive. You could use used Tesla batteries/with BMS for a far far less costly system. I was too worried about burning my house down. Agreed that my gasoline car is more likely to cause a fire than...
Ended up buying buying battleborns surge suppressor: Csl500 model. I did that so that each time I disconnect the batteries or breaker is tripped I won't have to parallel a battery charger to each open battery to get them online again.
Battery can at least stand 200amps for a half second.
By ohms law 50v/ 0.25 ohms gives you 200amps ....I would imagine that anything bigger than say 1ohm would work. Of course bear in mind that you could burn the resistor up if it doesn't have enough wattage to withstand the surge energy. Also...
The 60' 160, 80, 40m vertical on palm has raised (fence high) trapped coaxial radials. There is a tuner box with fixed L's and C's at the base. I also have a TR switched 160, 80, 40 trapped dipole on fence line for receive noise reduction....all on a small City. The homemade diy 35' telescoping...
See picture I just took and uploaded
300 watt renogy I bought from Homely Desp
Thanks for the compliment. Prod University of the internet n YouTube plus 3am cogitation!
Probably if I was a little less impulsive I would have done what you did.
Still not used to this forum
I attached some...
Use stainless fasteners around 2 1/2" long with star head. Predrill ....drive screws in straight....otherwise strip heads...stainless steel screws I bought very soft. If you start to experience stripping head....back it out immediately and replace....otherwise may not go in completly
The 1/4" thick square tube is a good idea because much thinner tube will crush and not allow u brackets to bind it to galvanized pipe. Yeah ask me how I know! Also not a good idea to use solar panel frame to tilt array....maybe break glass solar panel.
Yes problem is when you first connect or reconnect the battery. You may still experience battery internal disconnect....if you do use a 12v charger on each affected (measure voltage).
I used stainless steel u bolts and stainless nylock nuts....should last a while. Also I can easily change the panels when more efficient panel become available
I have limited space to install things....yeah most everyone does. So let this be a contest between the spiders and I...haha! Almost no matter where you put the equipment even in sheds the spiders somehow get in, however without without 4 walls and a door the likelyhood is much higher...you are...
I'm afraid I haven't been too careful on the labels in my block diagram. 220vac should be 240. The output disconnect should read 240vac output disconnect.
I did some trig and found out generally how to make the supporting structure fit the slope of the roof. The roof slopes in the opposite direction that I wanted it to slope....slopes to the North. I basically used the old idea that triangles in a structure makes it strong (parallels allow the...
I added a picture of a newly fabricated through box terminal. The old one was intermittent and got hot and burned a hole almost through a battleborn battery. The new one is made of bearing bronze (easy to cut on a lath or hacksaw and tap). The hardware screw, washer and lockwasher are stainless...
The L bracket is a piece of angle iron that is welded to the flat stock that is bolted to the array. The U bolts connected the angle iron to the galvanized pipe.
The insulator is plastic schedule 3/4" 40 water pipe and the collars are cut from schedule 40 cap....also could be cut from a schedule 40 coupling. Plastic pipe cement is used to bind the collar to the pipe. The collars are pressed together against the through wall metal. The water pipe should...
I bought a victron 712 monitor. The wiring diagram for the batteries shows two 48v strings connected to buss bars.
I bought the temp sensor. You can also monitor the midpoint voltage deviation....but not at the same time. So I used a spdt switch to do both.
Testing phase is next: Will it work repetitively? Soon as I get a better charger for standby in case it doesn't work and batteries disconnect. Old battery charger croaked
