Looking at your 6kw inverter

I  got that breaker in Sid, need some advice tho. I'm under the assumption that all breakers have a specific path flow, ie 1 side is line & the other load but this breaker doesn't have anything on it indicating which is which, can you help on this. Here's a pic of it

Check the label on the side.  Based on other GJ1P photos I've found on eBay, at the very bottom of the label will be the word, "LINE".  It is on the side of the label corresponding to the side of the breaker which is the LINE (battery+); the other terminal is LOAD.

The bigger multi-gang breakers (like the one you have) may have the "LINE" text much bigger and vertical on the side of the label corresponding to the battery side of the breaker.  Usually the terminal the switch sorta points towards when "on."

One of my brothers has played with battery desulfators, with similar results.  Obviously, for the record, we're talking lead-acid batteries (sealed or otherwise) here, not lithium batteries 😉.

I'd say there's probably something to it.  Still, lead-acid batteries have finite lifetimes, BUT...anything to extend the useful life is worth it.

I'd call it fair evidence if there was a control set of batteries that were only given normal absorption / equalisation / float cyclic charging over the same time and those failed to recover.

Yes, I did see it had line on the bottom of the label & another unknown 3 letter abbreviation adjacent to it that didn't appear to be a proper indicator to me. You'd think they'd have it stamped in the casing which was which.

Another thing is 1 end has a plate bolted to both poles while the other end doesn't so I'm going to just use it on the positive side & tie together the 2 separates. It doesn't seem that important to have both + & - poles on it.

It's a 170 amp but is that on each pole or just when combined & if 170 per pole, then does tying them together make a 340 amp?

On another note, the battery is the line side when it's being drawn from but wouldn't it be considered the opposite when the chargers are reversing the flow? Just wondering if that affects the breakers functionality?

Would make a lot of sense.  Seems I have a total of 8 magnetic DC breakers (3 different manufacturers), ranging in size from 10A to 150A...and none of them are marked in the casing.  Just the label. 

Agreed.  Especially if the battery negative is tied to system ground...not saying I recommend this, but it'd basically bypass the breaker if the negative was switched.

Not sure.  I would tend to believe the busbar on the LOAD side is missing...but single-pole breakers come up to 225A (GJ1 series), and they add more poles only if more amperage is needed.  Could you provide a photo of the label?  Working up the part number on the datasheet might shed a clue on this: http://www.heinemann-electric.com/acrobat/gj1p060701.pdf

Definitely a gray area; I'm not sure of the proper answer to this.  My general conclusion--and how they're installed in my system on the MPPTs--is that generally speaking, the only way you'll get enough amperage through them to risk a trip situation...is if the battery is supplying the power.

Here's the label pics. I'm surprised at the ease of flipping the breaker, usually on 1's of this capacity you nearly bust your fingers trying to flip it so thx for the tip Sid.

So the part number is:

GJ1P-H99-P-E-DU.

Works out as follows:

GJ1P = GJ1P-series breaker

H = Front Terminals

99 = Series Trip, Mid-Trip and SPST Alarm Switch

P = No Metering Shunt (one of the ones I got Sean has a 25mV shunt for measuring current!)

E = Bus Bar Connection

DU = UL-489 market compliant

I think the breaker kinda says right on the side that the terminals need paralleled 😉.

What I don't understand is the spec for width...your breaker is 170A, so should be a 1-pole width:

The width of the breaker is determined by the current rating:
100 – 225 A 1.5” (1-pole wide)
250 – 400 A 3” (2-pole wide)
450 – 700 A 4.5” (3-pole wide)
701 – 800A 6” (4-pole wide)
801 – 1000A 7.5” (5-pole wide)
1001 – 1200A 9” (6-pole wide)

Any updates on the status of the next shipment your expecting?

Should be delivered today.  Went via UPS, so the shipment kinda got broken up...2 arrived yesterday, and the rest should arrive today.

And I had better get to work on the code, get that parallel "daisy" mode working.

Alright! Great news, I'm anxious to get it in & fired up.

Do we get notified when our inverters are on the way?

Should get an email confirmation, etc.  Working on code right now, so far so good on testing the 2nd shipment of inverters.

Heya Sid, got a technical ?. If your inverter does well, I'll be ordering another eventually to daisy chain them. What I'm wondering is how you get 2 units to synchronize the sine waves so they don't conflict with each other? Is there a communication cable that connects between them to talk to each other?

Nope no Cable is required, other then you wire the second GS inverter different then the Master inverter.  the slave gets wired to the breaker box on its own breaker with l1 and l2 only connected to the input of the second gs inverter the Slave.   I am sure you got to go into settings and change your inverter to master and the other to slave for everything to work.  But the slave watchs the master by the shift in the Hz from what I understand from Sid.

Right now Sid is finishing up with the Dasy Code and I hopeing it will be done today and be pushed to other folks to update their inverts.
