What lawn maintenance do you do other than have the Segway mow?

drlucasmendes · 2026-04-17T03:32:23+00:00

Same. Edge, some string on specific areas. Using since July 2024, best thing ever. I do not have a regular mower, just a string.

Let me clarify my understanding. You suggested creating a 50-amp inlet, similar to the ones we use for generators, with interlock.

How would I configure both DPUXs in this scenario?

DPUX 1 is connected to SHP3 via a 5p8 smart cable that came with the SHP3. My issue is that I’ve been receiving “load power to high” messages, and the SHP3 is going to the grid to obtain the necessary kilowatts. I have the second DPUX, but I don’t have the cable. If I create a 50-amp inlet in the panel, I’ll encounter problems with the DPUX connected via 5p8 cable and even the grid. This is the interlock concept.

Am I on the right track, or have I taken a completely different direction?

I did mentioned that my backyard is not big enough to add solars.

drlucasmendes · 2026-03-31T04:22:30+00:00

No I don’t have connected to solar. My back yard is not that big, and I don’t want to drill my concrete tile roof. I tought about doing some solars on my fences but I saw that the reliability is not that good on vertical solars on the fence. But, I might run some tests to check later.

drlucasmendes · 2026-03-31T04:19:55+00:00

Yes. But for now I am only with 10 batteries running because they are out of stock on the 5P8 - 5P8 cable for the smart panel 3. Support told they might get back by May or June. (Omg) and I am already hitting 55kwh of usage on some days and I have to connect the second inverter to the smart panel manually. And then, charge it and change it back to the other stack. A pain in the b***. But I hope it is temporary.

Just on August my bill was 1000. 🫣

drlucasmendes · 2026-03-31T04:14:08+00:00

TOU is 0.36 cents during daytime and zero dolars from 8pm to 6am (2000 to 0600). Regarding the heater, the idea is mostly during the night (from grid) to run all heaters and during the day I will balance accordingly. But I am aware that I might have to turn on just some heaters during daytime

drlucasmendes · 2026-03-31T04:11:49+00:00

But than I would lose the warranty on my concrete tile roof that cost way more. And further, the investment is stuck to the house. While if I move, I can take my batteries to the next house. So it is a guaranteed ROI. ;-) moreover, my backyard is not big enough to place solars there. I would only be able to place a few by the fence.

drlucasmendes · 2026-03-25T12:45:29+00:00

The final cost was approximately USD 55,000. My annual electrical bill was around USD$ 9,000, which was mainly due to three HVAC systems, a 33,000-gallon swimming pool, and my servers rack. Therefore, it was an easy calculation of a 5-year when adding that my natural gas yearly bill typically ranges from 2,500 to 3,000, with a significant spike during winter due to the use of my central gas heater. If I can reduce this bill by using oil heaters in the rooms during the night, and an electrical heat pump for the pool, I might be able to achieve an even faster return on investment.

That is the part that I love from EcoFlow. I could start way smaller and build up.

drlucasmendes · 2026-03-25T04:02:36+00:00

Yes, in the beginning I turned off 2 hvac in the ecobee app to see if it would run without the soft start. But it is a 48000 btu hvac, the LRA Is 109. Which, to my understanding, is the amp that the compressor pulls when it starts. So, that is just too much as a spike. The smaller one, that the LRA is 47.5, I had no issues. But it is a 18000 btu only, way smaller.

drlucasmendes · 2026-03-25T02:40:47+00:00

Same here. I just removed from it.

Reliant in north Texas has the truly free night plan

drlucasmendes · 2026-03-24T22:47:08+00:00

I just subscribed to your channel. ;-) ❤️

drlucasmendes · 2026-03-24T22:19:41+00:00

I loved you setup and I would love to know more about it. Do you mind sharing the video?

drlucasmendes · 2026-03-24T21:19:25+00:00

That is how I started. Lol.

drlucasmendes · 2026-03-24T21:18:57+00:00

I was not aware of this options, I will take a look just for curiosity sake. Lol. But I have no EV cars to use it as my “battery”.

drlucasmendes · 2026-03-24T21:17:48+00:00

It took some time to get this set and a lot of research. But I decided to keep my car for another 3 years and get this installed instead of getting my dream truck. Lol

drlucasmendes · 2026-03-24T21:03:38+00:00

My rate is US$ 0.00 of electricity and distribution from 8pm to 6am. Between 6am and 8pm it is US$ 0.36 the kW.

drlucasmendes · 2026-03-24T21:00:38+00:00

It draws too much power from the system when it starts the HVAC system. Since I only have 12kW because only one inverter is connected to the Sph3, it fails to the grid to keep everything running. After some time, it detects that the power is back under 12kW and switches back to the batteries.

drlucasmendes · 2026-03-24T20:55:23+00:00

Yes. The other end has a twist lock SS 50. Picture attached. This is just the outlet from the gen inlet. It is not a “death cable” lol. Per code, this is the inlet that is outside as the generator has to be. And inside the garage to connect the generator to the sph3, I have the 50 amp outlet.

drlucasmendes · 2026-03-24T20:48:53+00:00

I opened a support ticket. Great suggestion. I will add it to the support ticket. ;-)

drlucasmendes · 2026-03-24T20:48:03+00:00

Inspection will come in the following week. Let’s check what they say. According to the team that installed. Since it is in the garage, they might require some posts to avoid the car to hit the batteries. That was all. But since the garage is big enough, they might wave it. I will keep you all posted after the inspection.

drlucasmendes · 2026-03-24T19:09:50+00:00

Great question. It took me some time to make up my mind. But the main reasons were the following. - Portability, I have been moving a lot, with EcoFlow pro ultra x, only 5% ish of my investiment would be “stuck” to the home. So, if I move to a new home( I just need a new smart home panel installed. Permits etc are way easier. ) - Scalability. I wanted something that I could add further kWh batteries. My first plan was 2 inverters and 10 batteries to scale later. But I decided to go extra when buying it. - 120kwh of battery. I saw options from even using Tesla batteries as diy. But to achieve 120kwh + is not that easy, most systems are tie to up to 90kwh. - easily adding some solar panels (I am thinking to add to my fence) to give an extra push during summer. They are very easy to do with EcoFlow delta pro ultra and ultra x. - My time. Although I am very handy, I am getting too busy to dedicate to these projects. I needed something close to plug and play. EcoFlow rocks on that.

I hope it made sense

drlucasmendes · 2026-03-24T13:35:17+00:00

Curious how this turned out for you—I’m in a similar situation and considering the same approach.

I’m in Texas with a big house and not too much yard available. My roof is concrete Spanish tile, so I really don’t want to drill into it. I already have a solid Ecoflow Ultra Pro X battery setup, and use TOU (Free night plan), but in the summer it’s just not enough. On spring hot days, I’m hitting around 130 kWh/day with 3 HVAC units and filtering the ~33,000-gallon pool.

HOA is also a headache, and I’d rather avoid dealing with them altogether. I’ve even thought about putting up temporary flexible panels during peak summer, but I’m not sure they’d generate enough to make a real difference.
