Merry Christmas and Happy Chanukah everyone! I've finally started to mess around with my 24 Volt Hybrid unit and have a charging question. My goal is to have this operate with Solar first then battery, then grid power. I only have AC power in and out and batteries hooked up at the moment(No...

You currently have 2 strings (serial connected) of 3 panels that are joined in parallel. Instead wire them as 3 groups of 2 (in Serial ) that are then joined in parallel. Using the numbers in your photo that would make each strings voltage 79.6 Or a max of 99.5volts temperature corrected...

I should add that I'm just learning about this myself and have more questions than answers. I opted for higher voltage panels which drives additional design considerations not covered in Wills all in one videos and schematics. I also wanted to plan for expansion, so every component and design...

If I'm not mistaken you bought the 12 volt mpp? If so you're running them in parallel. You also reported you had one battery that was blistered/ bulging? Take that out of the mix and see what happens

He just posted it yesterday so don't be hard on yourself. ?

Ok never mind. Apparently I needed to do a complete shutdown (screen off) to get this setting to take. Unit is charging properly now

Could you post more about your setup as well as the config settings your using? - Also what was the weather like for those two days - Sun or no sun

Ok so I think I have my answer - I just picked up 4 of these - Great price

Great deal but can only be connected in parallel:(

If you want something more permanent that gives you the ability to power just one thing via generator try one of these. https://ezgeneratorswitch.com/

odd then why is every house electrical panel I've ever seen mounted on plywood?

I've been going around in circles trying to determine the best way to panel this 24 volt MPP 2400kw All in one. It's a max 2000Watts solar input, Max 145VDC input., Max 80Amps in. My goal is to get the max wattage I can given the space and input limitations. I'm less concerned about...

I currently have 6 Lion energy batteries wired as 2S3P (285ah) and shared between 2 24 Volt MPP inverters. It's diagonally wired with a single Positive coming from one side of the bank and single negative from the opposite side. It stays well balanced. This battery is directly connected to...

I've been using the info from the ALT-E store to guide my setup. https://www.altestore.com/howto/recommended-inverter-cables-sizing-and-breakers-or-fuses-a62/. Based on a 3kw inverter with 200 amp dc input from batteries they say to use a 300 amp fuse

I'm pretty sure the Op's post was sarcastic. If not then I don't get what the complaint is. For 200 bucks more it could pre-built?

Well actually he did answer your questions and then some. Idle consumption can be high on these Chinese units and you need to plan accordingly. That doesn't mean you shouldn't buy it it just needs to be accounted for in your solar production and battery capacity. You can most certainly run a...

Reading I recall reading the 2017 reg changed this to 1 meter from the array

Yes but in your post above one battery is 29v and the other is 26v. If that is in fact the case that's a no go. They should be balanced

I have two MPP Hybrid units each fed by it's own 1300 Watt array. Each inverter is powering separate AC circuits via a reliance transfer switch. What I'm seeing is that when the load doesn't demand it the PV doesn't produce as much. For example if the load is say 250 Watts the PV may produce...

Thanks - Done

It's 60 bucks to join. You can do it online

Much of this conversation has been about requirements to support pass through. However, don't lose sight of the fact that the inverter also needs amperage to charge the batteries and could be doing complete pass through at a full 2400 watts as well as charging the battery at the same time at...

Except I have a GFCI dc breaker(required by code). on the PV input side that requires me to ground the breaker to the inverter as well as the ground rod outside (also tied to the combiner box.) I connected that ground to the mounting screw near the battery input mounts Any issue with that?
