Hello Mike, Welcome to the forum. If you haven't already done so, I suggest you check out the resources area and search the forums. Its faster to read an existing thread on a subject than wait for responses.

Mine do not do that. I have no grid connection. 1 inverter n/g bond in place, 2nd unit n/g removed. MDP has isolated neutrals Gen has n/g bond

How are you determining the 80% SOC ? I have the same setup , and my units are both in USE . I have set the batt charge parameters for both inverters to the specs provided by the battery literature. The comm cable is disconnected . My batteries seem to charge completely. The SOC lights...

The 4/0 cable requirement is a product of the total potential load. It has nothing to do with the rack itself. If you have 2 - 6500w inverters that's a potential load of 13,000 watts / 48vdc = 271 amps. This is where the 4/0 wire requirement originates. The wire must be large enough to carry...

The earth anchors are a solid idea. I've seen the power companies use old tires buried 5ft deep with the guyed wire attached to it and the pole. We had to remove the old poles and those wires and tires were the hardest part. We would hook a 14k pound excavator to the wire and pull . The cables...

7yrs in the az desert with no cooling or running water??!! That's impressive.

The rating on the wire is its max. If it's 600v ac then you can use it on any ac power less than 600v.

Are you running this wire exposed on the surface? If so that's your biggest issue. If your running it in conduit you can use appropriately sized thhn/thwn type wire. Pv wire is rated for exposure. If you are just laying it on the ground you will need wire that is rated for exposure. You can...

I looked into that and according to what I can find the dirt is still 85 deg. 6 ft down

You are correct , a homeowner may do his own work. This applies to any trade, roofing, plumbing , framing etc...

I would use Polaris connectors. Polaris is the brand , electricians sometimes call them squids. They are insulated , weatherproof , have good wire range sizes , no crimping required and are reusable. They can get a little spendy, but they are quick and reliable. You only need a hex key and...

This is all true, but if you have an ungrounded electrical panel and you introduce a short to ground current will still flow to ground. This is what makes an improperly grounded system so dangerous.

I have used similar zip ties numerous times. They work very well as long as you have a decent tie gun. A crappy tie gun makes them very difficult to get even remotely tight. In my opinion Grainger is overpriced when it comes to electrical parts. Most wholesale electrical parts distributors...

Sorry WY , I spent 20 yrs at 5800 ft of elevation in Utah dealing with all the B.S that goes with that... never again!

Same inverters and battery setup , starts my old definitely non energy star rated 2.5 ton mini split with no issues. I have the battery cables that came with the Batts as well. My batteries tie to a bus bar individually, then bus bar has 2/0 wire to each inverter, via appropriate ocpd.

Out in the west meters on water wells are nothing new. It's in place to make sure you do not exceed your water rights. If you have 1 acre feet of water rights, that's all you get, the rest belongs to someone else......

I actually use that app as well. Once I got Watchpower installed I was disappointed I wasted so much time getting it to work.

BentleyJ, and Don B , You guys are 100 percent correct. Ac is by far the biggest issue. Six months of the year the low temps are 70- 85 deg. and the highs are 88-98 deg. There is also considerable humidity. The home will only be occupied by 2 people. The previous owner only used the home in...

Table 310.16 covers not more than 3 current carrying conductors in a raceway, cable or earth. (Direct buried).

Anyone else having issues getting the 6.5kw eg4 inverter to connect to a local wireless network? I am using the app (powerwatch) provided by the qr code in the manual. My android phone can see the wifi module of each of the inverters. As per the instructions, I connect my phone to the wifi...

I spoke with tech at SS and they said it was losses of communication with the batteries. The tech attributed this to the data cable being bad...we shall see......, mine charges for hours at a time no problems, then it randomly throws a 61 code. It does it everything it finishes charging the...

I have both mine set to "user" and no RS comm connection.

No offense taken. My question was more about the flex max 60 controller and whether or not it would have issues being tied in this way. I'm unfamiliar with this product not the proper method of wiring.

Conduct a solar audit( figure out how many kwh of electricity you will use daily) you can find wattage data online for most devices. Example: A 1000w device running for 4 hrs daily is 4000 watt hours or 4kwh . Add up all the devices, get your daily total. Your daily/monthly usage will define...

I have 2- 6500ex48 inverters, one has the ground neutral bond screw removed. The other provides the single neut/grn bond location for the system. I have a 4 pole transfer switch , when using generator power ( 4 wire 240/120vac) , the generator neutral is floating. It's a honda eu6500is...

I sold my house and business. Moved to Mexico.

I chose 2 smaller inverters for redundancy, and future expansion. If 1 inverter goes down I can still run my critical loads. I am off grid in Mexico so getting parts is not an easy task.

We were taught "never saddle a dead horse" . Saddle the live side.

The NEC has requirements for backfed breakers, they must have a way to be "tied down" in the panel. If the panel has no provision to do the tie down , then it's a code violation to back feed it. I used the main lugs on my panel as well.
