I would like to buy using the forum, as new prices are a bit out of my budget at this point. Any other tips of successfully buying over the forum? Did this seller ever make you whole?

These are great leads...thank you DIYrich! I'm running 4S2P(not good at the aconyms, but 2 parallel strings of 4 in series) on the roof; panels are in hand. Ground installation is not an option unfortunately. Here is my schematic of the system if you are at all interested (pieced it together...

So if I may paraphrase, these balancers are not worth it? In my instance, I have 4 SOK 12V batts in series. The voltage difference of ~0.1/0.2 VDC would not maximize the battery charge/discharge cycle enough to be worth the investment? The batteries will likely outlive me, so I'm not worried...

It worked out so far. Took off minimal metal, centered the fuse and fits perfectly. When all is said and done, I will shoot the whole kit and kaboodle with an IR imager at peak load.

Using the following T class fuse: https://diysolarforum.com/threads/victron-putz.65631/

stupid question, why would anyone want or use 2FA on craigslist? The only thing I use 2FA for is to log into accounts....

Good catch! Yes, I counting on my single phase for 4kW.

Hello forum members. I was hoping for some input on this. I picked up a 5kVA Victron inverter and the online manual specs 2 AWG from the AC1 output...holly cow. The manual also states a max capable current of 137A due to the 95A AC shore input, which I will not use. So, I will never see...

Working from my electronics education memory of many moons ago, the voltage determines the gap jumping ability...the greater the voltage, the greater gap the electrons can cross/arc. Specs are important to me, because an engineer made some calculations based on a user requirement specification...

whoops, CS beat me to the reply....disregard.

Hello Dexter @HighTechLab , any update or any information whatsoever on the UL listing of the 5kVA multiplus ii? Thanks!

I haven't decided on grid tie or not. Is this definition of grid tied: power goes back out to the utility? I asked earlier, but no one responded: https://diysolarforum.com/threads/permit-related-off-grid-definition-and-emt-use.72124/ Yes, I'm in California. For our county in California, my...

If I'm reading this right, how does a BMS prevent battery discharge but retain voltage at the terminals? Wouldn't that still allow discharge?

Thank you all...I'll keep it!

Just received this Carling/Midnite breaker and wanted to get feedback. The brass post is well connected (riveted?) to the steel terminal, however the entire post/terminal assembly is quite loose/moving around quite a bit in the housing. Is this normal? When the breaker is on, movement is...

Still looking...anyone out there?

yes, the 12K is on the 3 lists: https://www.energy.ca.gov/programs-and-topics/programs/solar-equipment-lists My permit person and installer person said they are a go to inverter....

Thanks Zanydroid, I will look into SunWorks! At this time I'm not interested in acquiring insurance....

Looked unsuccessfully for a similiar thread for this scenario: when the battery hits low voltage cut-off, is the MPPT at risk for damage due to presence of PV voltage and an open battery circuit?

I'm still getting my head wrapped around the Victron equipment. So, if I have this right, using Victron MPPT, Multiplusii and a Cerbo, I can have: utility power with the M+ and it acting as an ATS; utilize the batteries for the loads to a specified SOC per the Cerbo, and pass on excess PV power...

How does one tell if "A 12V battery [has] a 48 volt rated BMS = 4 batteries in series?" I want to put these 4 SOKs in series, and the cut sheet says this is possible. But no where do I see the BMS is rated for 48/56 volts...

I'm scratching my head on this install, and it's probably an obvious answer starting me in the face on this single phase inverter. I'm hoping someone has the interest / is able to describe this connection in this youtube video. The installer seems to be running the 120V inverter out single...

Hi Technodave, I went to the midnite solar site and I don't see them selling anything, I don't see a cart. I do see them pointing to distributors for purchasing. Am I missing something? I too am looking for a "box" to panel mount a midnite breaker.

did you find a box for the breaker?

Is it possible to post pics of your system?!

Thanks Eggo. Yes, I noticed the 4 in series spec, so the 48 V on the BMS is implied...I guess....I hate guessing. Also, yes, I was planning on the balancer. I looked at the Victron, but 3 are needed for 48V! For holding the batteries at elevated voltage, this is done with the BMS overvoltage...

right. But per this video his dryer/other 240V loads *breakers* are on the bus with 120V nonsplit phase/single phase, correct?....how would these loads be satisfied by 120V?
