Look at the blue sea latching relay ml-7700 below

Thanks for all the comments. This opens up a new world of possibilities. I’m using a Sterling bb1260 but I was thinking about an intelligent way to parallel my FLA. I have done a few videos on this ml-7700 latching relay that can be used for this application I think. . I also dis covered I...

Maybe a bad lin. It says SPL-Booster: the Swiss-Army-Knife-for-Sound-Pressure-Level Meters

I have done several videos on my Enphase IQ7+ / Ironridge / California Permit / Main Panel / labeling / troubleshooting / testing / tax. Here is my playlist https://www.youtube.com/playlist?list=PLCal7Co3mAHSR5tg48M8NGKBcjBso8Wle

I like the ads1115 here is a 4 channel i2c breakout. 16 channel on one bus https://cdn-learn.adafruit.com/downloads/pdf/adafruit-4-channel-adc-breakouts.pdf

Thanks. Great explanation. I’m afraid of paralleling my 200a FLA and 150A LiFePO4 over a 6awg wire I’m using to switch my solar charger to charge the FLA and LiFePO4. What rule could be used the safely parallel the banks? My LFP bank is normally at 13.4 90% SOC for me and FLA maybe 12.5v 95%...

With sbms0 you can decide to keep your battery always connected on shut your charge /discharge sources down and I will have a auto battery switch that will shut off my house bank as a backup fail safe for house. I’m just afraid of depending on a home built battery pack to start my engine until...

I have a Balmar 100A alternator and my MC614 only lets the alternator run about 40-50 amps of long periods of time because of alternator overheating. Yes. I can run 70A for a short period of time. I also have issues with a narrow alternator belt and strain on my water pump so running high output...

It may make sense to keep your lead acid charging systems and add a DC DC charge. Then you can slowly migrate to LFP after you know how/if everything works. Here is my current system that is migrated.

for balancing. Also check this out https://diysolarforum.com/resources/top-balancing-lifepo4-cells-using-a-low-cost-benchtop-power-supply.65/ . @FilterGuy is a very trust worthy source for info.

Here is my balancing video. I think most would a agree that you should top balance in most situation. Will also has a video.

Some wiring details and testing I did to prove to myself that the wiring was good before the panels and microinverters were installed. I use a voltmeter to test stuff out and show what a normal system looks like from a voltmeter perspective. I also propose testing of the Q cable. This is for...

I'm documenting my install of the very thin ribbon cables. I'm using heat shrink adhesive lined terminals. Will also did a video.

I just made a discovery. The Blue Sea ML-RBS 7700 only takes 7mA of current on the signal wires. It is the red wire that takes all the current. This means that most optocouplers can drive these circuits if they have 10ma available. Here is my video of the testing I did.

The The system was for my house and was Enphase. Here is where I look at the option of paying a small amount more for the IQ7+ Enphase. Many people don’t agree with me on the value of UL. I needed to create this follow up video to pitch an alternative UL system. . Sorry another video.
