The unit was not charging because I forgot what model I was working with. It requires 120VDC minimum at the input to work. And it has a max input voltage of 250V. I don't know how I messed that up. I was just using the 148VDC max model the day before, so mixed it up.

Also, use the proper terminal ring hole size for your inverter. I use these on multiple inverters, so they are huge.

Coming from someone that has gone to school for Hybrid vehicles and high voltage systems, always assume there is voltage at the terminals until you check them with a multimeter! (You should always check with a multimeter!) never assume a high voltage switch is operating properly until you verify it!

Retired elevator man here. When working on live circuits. Keep one hand in your back pocket. Less chance of going thru your heart. When engaging a disconnect turn your face away from the switch. When it goes south they explode like a bomb.

Hi, Will! We are older folks who have interest in this kind of thing, but are rank beginners! It is always a pleasure to watch your videos...you do an excellent job explaining things to us folks just starting out!
Keep up the Great Job!
God Bless!

[hendersonsobers]

The 'only' downside of touching a 48v full battery is instant death! lol. love your videos man. i've learnt so much from this channel.

[spencercre]

As a newbie, I have never commented on anybody’s videos. Until now. The value that you offer is among the highest I’ve ever seen. Your degree of clarity, matched with your passion, is outstanding. As a general comment, keep it up. We all very much appreciate it.

[iztherelife]

Well this is funny timing. But so thankful. We’ve put half of our 10 kw Growatt system. And been using it, a month. We bought the other array and got it installed last weekend. Today, my husband will tie that array in. We’ve gotten 2 of the 6 batteries in. As soon as my husband gets out of bed this morning he’s going to watch this. I’ve been worried about tying all the components together, but Wonderful Will has been helpful all the way. Thank you!

[bucknaykid]

Thanks for going over the simplicity of the set up. I will be looking for the video where you build a bigger system with more batteries and can show the proper set up of the bus bars and those t fuses. Thanks for the reliable information Will!

I’m a Union electrician in NYC. 35 years experience in ALL phases of electrical work. 48V is the line of delineation between “high” voltage and “low voltage. It also separates electricians from data technicians mostly because back in the day most telephone circuits ran on 48V systems. And to be honest 48V kinda tingles a bit of you get hit by it. You would never want to be holding it when the phone rings. That closes the circuit and that’s when it hit’s you. It’s a long running joke amongst veteran electricians.

I would love to help you out when you decide to start enclosing your wiring in some conduit. Good job Will

I suggest a cheap lock out tag on breaker. Even a piece of tape over breaker reminding you to double check before removing tape.

Even a quick check list before you remove tape.

Man - I dont personally have a solar system - yet. But the enthusiasm that Will shows during his videos is great. Dude genuinely loves doing what he does and it shows.

[mmpiano]

I like the simplicity of teaching here. Another thing to consider is if the person is still leery working with the voltage on the solar panels, they could wait until it's night so the voltage and amperage of the panels is at its lowest.

[tonynunez]

You do a great job explaining very complex and dangerous equipment. I appreciate the way you emphasize safety and explain how o.1 amps of current can kill you. Thanks for making this so easy to understand.

[justinmatson]

First time I've ever felt like I owed someone money for knowledge.

[evolvingskills]

Would love to see a larger 48v system for off grid home, especially how to wire the panel if thats possible.

[rebeccafox]

Will! You're amazing. I have a similar history as you, with the medical issues and surviving in an RV without family help. Doctors have been no help, so I started reading medical journals and dictionaries to figure it out for myself. After years of struggling, now I'm healthier and have my RV gutted, about to buy a 48v hybrid system and a mini split to install. Thanks for putting your inspiration out there for us. :) I'm glad you're getting along better now.

[marcarcher]

A lot of times I don't ever plan on building some of the things you have videos for BUT I still watch them because I ALWAYS learn something new. And also your presentation is awesome!
Thanks Will...

[glleon]

Great and needed video, Will. Solar is a great hobby but high voltages will kill you. These all in one systems are very safe if you are careful. I am an electrical engineer and Will’s practices in this video are rock solid.

[zhuanjifarms]

I know when I see the 'plywood blank canvas' up, I'm in for a Will-full edu-ma-cation fer sure!
Thanks and gratitude for all your enthusiasm, open-source info and holding these manufacturers to account for shortcuts and shortcomings. You da man Will!

[paul.phillips]

The hardest part is coming up with the coin to buy all the components. :)
