It's all fun and games..

Post by raysun »

So I've decided to upgrade my off-grid system and the fun begins...

Upgrade items and reasons:

* 3kW Flexpower One to 6kW Flexpower Two
1) Easy bolt-up, plug-in and play with minimum risk of letting the magic smoke out.
2) When I added a 2nd FM80 to the FP1, I swore I would never touch the internal wiring of those cramped wiring panels again.
3) So my dear spouse never has to ask: "Can I turn on the...?"

* 48V @ 350AH SLA battery to 48V @ 450AH LiFePo4 battery
1) Lead Acid just isn't expensive or twitchy enough.
2) Let's me hang with the cool off-grid kids.
3) Because the guy at the counter ahead of me BOUGHT TWO ENTIRE PALLETS of Phi 3.8s - my local supplier's entire shipment. 🤨 My friendly salesman who PROMISED me batteries for delivery on the 22nd took 10% off my order price for not going Rambo on the guy. I said "Mahalo" with aloha, but still followed the guy out of the parking lot, contemplating my other options.

* 10 325W 72 cell panels to 10 440W 144 half cell panels. (One array swap of two on the roof.)
1) Impulse buy, sort of like chewing gum and the National Enquirer (headline: "Man cuts off own head with chainsaw, AND LIVES!") by the checkout counter. 440W @ $200. Pretty good for the central Pacific.
2) I'm tired of the FM80s not sweating bullets.
3) A kW here, a kW there, pretty soon it all adds up.

All the old stuff is sold to a fine young man. Army vet with two tours in Afghanistan. Combat disabled. Carving out a new life for himself in the wilds of Hawaii Island. Happy to help keep the lights on.

Its all fun and games, until someone loses an eye. Then its just games.

I'll let you know how the install goes.

Yeah, but you on-grid guys are all talking about "Feed in", "HBX", and all kine stuff I don't understand. Makes me feel dumb when I eat lunch at that table.

Holy Cow Raysun that is a heck of an upgrade I tell you.

I am impressed by your system.

Cudos to seeling your stuff to a person who needs it and will appreciate it as well.

All I want to do is put up 6 LG BiFacial 400 watt solar panels on the sweet south-facing roof at my house.

The extra 2400 watts would help in the winter and in the summer I would then go net metering with the extra.

Future plans.

Our 3kW system has served us without a hitch for nearly 5 years. I can remember the first day I turned it on, I was so nervous about battery discharge, I cautioned my wife not to turn on anything without my checking the system.
I couldn't sleep until I collapsed from exhaustion. When I woke at 6 in the morning, the first thing I did was check the system: battery SOC - 97.5%. LOL!

I told my bride she could turn the lights on.

Since then, we have increased consumption to match capacity, naturally. Being off-grid, there's lots of days we leave "power on the table" because we don't have anywhere to put it.

Its 75 vertical feet to the top of my property. Maybe someday I'll put a 10,000 gallon water tank up there, pump my domestic water to the top of the hill, and put in a micro turbine to capture electricity as we draw it down.

We have a very large bath tub. Our guest house is really our bath house.

I tell guests that hot water for bathing is limited to 7,000 gallons.

That is a big ass tub............... :grin:

I 6 foot 6 inches so I would enjoy a shower and tub sized for my height.

My system has been in for 4 years almost now and trouble-free. Well, I had an FM60 go bad but it was used and had a hard life before I got it.
Inverters were made in 2008 ish I think but never installed, So I got all new boards, FETS, and cards from Outback and installed them.

90 percent of the house runs off the system during the summer that is, winter just sucks here.

The tub is actually 70 gallons, so my 5'11" self becomes buoyant when filled (fat floats I guess.) Its large enough I can be submerged to my neck.

I tell guests there's free refills.

Looking forward to reading of your progress.
Assuming you mean the supplier in Shipman, my installer told me the only way to guarantee SimpliPhis was to put deposit. Have to wonder who was in front of you as my installer said when he got mine, he got all in stock as well and the guy behind him wasn’t happy either. Apparently popular battery.

Your water flow idea sounds too familiar as we have a similar, but opposite situation. Our cottage is at the higher end. For too long I tried to convince myself there just had to be a way to move he water and get power.


I installed the Emporia Vue monitoring yesterday. Not enough data yet

Inter Island solar in Kona. Vince got me batteries from Hilo.

Too many rich folk moving up the Kohala coast to escape mainland COVID-19.

Guy was complaining one of his customers was complaining about the color of the panels.

😂

Even down here in dirtbag Ka'u, so many new faces. My Hawaii Telecom guy said he used to service all West Hawaii from Ka'u to North Kona. Now, he only does Ka'u because of so much new work. They put in gigabit fiber here. WOW! Its been a long time since I've had this kind of throughput.

Its 75 vertical feet to the top of my property. Maybe someday I'll put a 10,000 gallon water tank up there, pump my domestic water to the top of the hill, and put in a micro turbine to capture electricity as we draw it down.
The company where I used to work had a part ownership in a pumped storage plant in Pennsylvania, near the Rolling Rock water supply. I think it was good for about 200 megawatts for about 4 hours, but I didn't read the link and memory is the second thing to go - I forget what the first thing was.

A neighbor down the road from us put a hydro unit on a 'Unique" well. Here in WA that is usually a capped underground spring. Stories have it that years ago when the local driller hit this spring at around 20' down that it blew a 6" column four+ feet out above the ground. They had to call for an emergency load of concrete to plug the hole. Later they returned to drill through the concrete plug and set a 4" steel liner in place with a gate valve. So the neighbor did some research and put the hydro unit in place. There were back and forth things with the impeller and programming to match the water flow/pressure but finally got it tuned. He buried a long haul of wire up the hill to his cabin plus 1.25" pipe to pump water up from a 750g storage tank down below (350'+ of elevation). The hydro ran at approx 300vdc but was amazingly low output. And he had to run a generator to power a well pump to transfer water from the lower to the upper storage tank. It seemed to work well until the property sold. Overall I was not impressed with the output of the hydro project.

At this time there is a major project getting licensed for a hydro project pumping from the Columbia Gorge to the tops on the Washington side (from excess of the wind turbines as available) and generating power as the pumps reverse and become generators as the water flows back down. This is a really cool project and is getting a lot of attention. The efficiency is also pretty cool.

Overall, this reminds me of the stories of the folks that have put in wind generators but the overall cost vs return isn't what they received. And the personal hydro in this one case is not what the cost vs return was either. And, for the neighbor's system, the water flow has declined as the seasonal droughts have gone into the 8th year. There isn't too much above him in the same watershed but I bet there are some wells going low if the well owners were around full time.

I know you are teasing about the shower/bath stuff but I want to impress that it takes A LOT of water to generate usable power. And 75' at .8 per foot seems cool - if you could use it 1:1. So far it seems the commercial grades of wind and hydro can do it well. The personal systems are questionable. I submit myself to being humbled based on the above.

Best,
Jim

The plant in Seneca, PA took advantage of low grid prices at night to pump it up. Several nukes in the area with "must run" charters made it possible. Most all the coal burning plants in the area have shut down, though, so i don't know if this plant is still viable or even if operating, altho' wikipedia says it is.

While it is off in the future I loved that batteries could be made of remnants of nuke stuff and be relatively safe. Hopefully that is researched fully and with funding. I don't live close by nuke stuff, other than Hanford, but I really love the ongoing research. And, with reservations, I like nuke stuff going forward. Esp. if it can be safely reused.

Its a big bullet to bite. 4-5 years from now, lithium or its replacement, at the consumer level is going to be 10% current cost/kW, mark my words.

I could bet I'm right and put in another set of VRLA, but decided to go with the high-priced spread.

When I look at the charging curve of my friend's system in Haiti, I'm more convinced than ever lithium is the way to go.

Since you went for them I suspected you had a good reason and backup data.

I also bet that baths and showers have little to do with this (wink).

A Radian system, grid tied with 2 hours of grid power/day average. 8 Phi 3.8 (600AH) drawn to 25% SoC overnight.

Bulk charge to 56.4V. Done.

Never use 'em myself.

I wonder why the dogs sleep in the bedroom, and I sleep in the dog house?

He's grid tied. Easy to see he can afford to run 1500 watts of load overnight. I'm sure you're much more frugal.

Yes, they are grid tied, but its really unreliable. They usually see less than 4 hours of grid electricity per day. Its often so dirty, they have to switch to Generator mode to use it.

The facility is a mission school/orphanage. They use a lot of juice. We, on the other hand, ate just two people, but use a lot of juice, considering. ;)

Thanks for the clarification. They must have a lot of PV, considering how fast battery voltage rose before the grid came on.

They burned through two L16 battery banks before they took council and upgraded their PV to about 10kW.

The Phis charge fast. That's one of the main reasons I opted to blow all my lunch money on a set. We get pretty reliable sun for about 3.5 - 4 hours a day - mostly before noon on most days, before the clouds roll on. Being able to charge to a target voltage and be done with it is a nice attribute. There's lots of days, even with fast charging (for lead acid) AGMs that its a challenge to get Absorb completed. My neighbor, who uses about 1/5 the power that we do, and has a similar system, though 1/2 the PV, is chronically undercharging his L16s. He will be due a battery change much sooner than would be necessary otherwise.
