I guess I'm far enough along in my build that I can start posting some pics of my ground mount. Here is 12 bifacials on a pergola that I extended to cover my whole deck: I have an 18Kpv and 6 lifepower batteries. I'm still waiting on my electrician to wire up the 200a disconnect between...

I built a pergola a while back to hold 12 panels. I did concrete my 4x4's into the ground tho about 3 ft. I went out there during a storm recently (60-70mph winds) and the thing was barely moving. After that, I'm not too worried about wind on my pergola. As to your issue, they do sell metal...

I probably could enclose the tub, but I'd loose the sunset every night.....

So a few years ago, I bought an old broken down hot tub for $300 and restored it to working order. This took me about 2 months since all the frame wood was rotten and all of the jets were leaking. I re-sealed everything, rebuilt the 2 main motors and added an additional circulation pump for...

Originally, I was thinking about doing the same thing, but after I got my solar and battery backup, I realized there is loss when you convert from AC/DC, and in this case, you convert AC to DC to put it in the batteries, and then convert DC back to AC to use in your house so just know it's not...

I am pretty sure it was vertical before it fell. The delivery guys supervisor attempted to convince me they were OK, but I said no.

I'm running all 12 of my bifacials in series. On a sunny day, I pull about 5000W or 22kW per day

No, I just finished installing them in late October! I am planning on adding another 12 panels on the roof of my house, but I wanted to make sure I knew what I was doing before I committed. I'd appreciate a link of course! I live in Houston Tx, and the humidity here is pretty high. I don't...

I wonder if you need to flash the firmware on the batteries and set the dip switches to the correct #'s for all 9 batteries

That's an interesting idea! I have a very old hot tub with a large area where the filters are located. There is plenty of room to add a heating element here. I'd have to be able to control it so it doesn't overheat the tub tho.

I got on craigslist and found someone that had a whole bunch of the unistrut for $10 a piece (I bought 10). I used lagbolts and huge washers to attach the unistrut to the 2x8's. I used 1.5" 1/4 bolts with washers to attach the unistrut to the solar panels. It feels super strong. Lastly, I...

I just pulled the trigger on the 18kpv, 30kW battery and 12 460W bifacial panels. I am going to add them to the top of my pergola in the backyard (no shade at all). The panels will be about 35 ft from the inverter. I was planning on running a single set of 10gauge wires in metal conduit to the...

I need to wait a month to see how my avg kwh changes, but here's some rough #'s Old system used about 660 kwh per month Estimated new system should be about 32.4kwh per month and most of that will be the circulation pump, not the actual heating part

The inverter and battery system I am planning to buy is 9540 listed : https://signaturesolar.com/eg4-18kpv-hybrid-inverter-system-bundle-30-72kwh-eg4-lithium-powerwall/ I was just joking with the big battery comment and wasn't specifying a particular brand. The specific question I really need...

I can't imagine what the original poster thinks when he comes back and reads this :)

Did anyone with 18kpv not have their datetime not update with the time change? I have mine set to GMT-6 (I live in Houston) and it's showing an hour ahead. Thanks for your help.

Ironically, I just got a call from the freight company to schedule a delivery of my battery rack today.

Today I received my whole solar setup of inverter, batteries and panels. First pallet came off without a problem, but unfortunately the 2nd pallet got away from the delivery guy and all 600 lbs rolled off the back of the 18 wheeler! The delivery guy took full responsibility, and got it back on...

Ha! I love it :) inspiration fuel...

I have a thick cover, but not a floating one. I added a lot of insulation between the fiberglass and the wall of the hot tub. Just went to Home Depot and picked up some rolled up home insulation.

Seriously, why are people such jerks? He literally wasted his own time to post something useless that doesn't help anyone.

Are you assuming people don't know what he means when he says 18k? You are delusional.

I'm not sure I understand. Are you saying 12 is too many for mppt1?

Ok, I completed my hot tub project this week! I ended up buying a wifi controlled smart switch that has a temp sensor: Inkbird 308 wifi It connects to the tankless water heater and turns off when it senses the temperature at 98 degrees. I put the circulation on a basic smart plug that...

Something similar happened to me, I have 18kpv + Lifepower4. One of my batteries got so low, it shut down and the rest went on charging happily. It ended up being out of balance badly enough to slowly get lower and lower voltage. The solution was to separate out the one battery and get it to...

I used facebook marketplace and found 75 ft of 3/0 for $200. Also found 2 500ft spools of 10g for $75 each. I thought it'd be useful in the future when I add more panels.

Good luck getting one of the 6 slot ones. I've been waiting for 6 weeks for mine.

I just read that a heat pump is a bad idea since hot tubs usually sit around 98 degrees and in the cold winter, there's no way it can pull enough heat out of the air.

if you lower the kw of the heater, wouldn't it have to run more often to keep the temp of the water high?
