Very new to solar but started purchasing items, not sure of the final specs of the whole system.

[kromc5]

Few more items came in, wanted to clean up the 12v wiring and added bus bars. Batteries are still doing very well even during discharge.
The connectors are to allow moving the charge controller between banks. I was unable to delete the chart data to correct the -200kwh but if you re-install the program it removes the data. Still unable to contact batrium via, email, phone facebook.

Solar assistant got an update and has mppt charts. It's not to cold yet and the load from the hvac looks to almost triple energy usage during the evening. With dual 4p16s the voltage sag with the hvac, mini split running is reduced by .5/.6v which you can see in the 3rd chart.

Will be great to finish the other panels which will mean positive surplus even with the 5ton hvac and mini split running together plus everything else. Just barely got the backhoe under the panels to dig faster. Found a coax cable twice they did not mark. Very odd, since this side is just woods is a secondary road to the back, no homes etc. Plus, when I moved in there were no coax providers only dsl.

Was able to get one array online and the run was roughly 98ft, 186.5 at combiner, ran in and got 186.4. The 250v is much more accurate than the 150v which is .8 off. Almost two weeks and unable to contact Batrium.

Both banks are doing well just need to dial in the new charge controller settings, before they rarely went into bypass.

 

[kromc5]

Got the 2nd charge controller settings very close and both banks are staying near perfect.

Slowly cleaning up and getting everything ready, the eco combiners had a suppression built in. But since I had ordered them all way earlier I decided to put them in. I very confident the midnite is much better. Had to drill out the connectors to get the 4 gauge into the combiners. Valve broke right off the bat and it created some art work, titled make me run around trying to finish everything before it runs out, for sale immediately 100 billion dollars.

Cabling really adds up ran out again but finally done with that. Midnite AC surge for each panel, getting ready to mount the 4th 250v charge controller.

I just built the frames for my ground mounts.

Nothing but rain and clouds the past 5 days with the two large banks just barely getting to a full charge each day.
10:15 AM and this is all I'm getting from 48 500w panels. Of course this does not show the two charge controllers
which gives it a total slightly over 570watts.

 

[kromc5]

Wow clouds are very thick now down to only 470w from 48 panels.

Purchase more of the older eves for spares since they are being phased out, also from Hayley. Getting rid of the older 5ton unit for a new 3ton Mr. Cool but came in damaged. Since we use a mini split down stairs I no longer need the larger unit. The old unit is heavily rusted from where the pan and become mostly clogged. Flooded the basement 3 months after moving in. It took a bunch of work to clean it up. Plus the outside unit likes to freeze up and the heat strip turns on when its 70f outside, lots of issues. I'm very interested to see if the loads are less with a smaller much more efficient unit. The current unit is roughly 14 years old. I will test the second batch of batteries and post, they appear perfect with zero issues found. The old one had a 15kw system I purchased a 10kw heat strip and will unwire one side to reduce the load.

The batteries have diverged some due to not getting close the charge settings, yet to get over 53.88 in 4 days with storms and very thick cloud cover. 48 500w panels and the 10amps is about the average which is very low compared to the 48+ amps at this time of day. Cloud clover definitely cuts more power than I had read in articles.

Since its been raining I have just been working on the hvac and wiring. Getting the lines routed has been very tiring, the large pipe is very hard to get routed. Moving it 1 foot is a major undertaking and I call it a day. To keep the basement open they used a steel beam the entire length of the house making it very difficult to get around it. Also ran out of steel 3 inch pipe and its doubled in price, short 4 of them. Due to not having any level ground it was not easy to estimate them but was decently close. I have 18 more panels to mount somewhere. After watching the cloud cover I may make another charger a floater. I wanted to have two charge controllers for each panel. But with winter coming I may need 3 on the heating side, I'm not sure yet.

Can anyone tell me if the SPF 12000T DVM model have 2 MPPT charge controller? I think it does and I'm trying to find out if each can take Voc of 250V from the PV array? Thanks

It has dual pv inputs with a combined power of 7000w.

Took me 5 days to run two 50ft lines plus new thermostat line, the 3/4 was very difficult to bend through. Few pics of the inside of the 3 ton unit.
Zero light flicker when this one turns one.

Weights 217lbs.

Now the great part took the large readings from the old unit to the new unit and its a 55% difference.
5 ton Old: 5498w
New 3 ton: 2452w

Also installed the ecobee lite3, the system had a common but if you do not it’s a great choice as it comes with an adapter.
I have 10kw coils in the system and disconnected one row just in case.

This units condenser coil is about 1/2 the size of the old one.

Was that 2452W with or without those resistance elements powered?

It was without those running, I'm hoping they will not needed for the winter. The old 5ton pulled over 19500w when they kicked on.
