Awesome job, some conduit will easily hide the DIY side and make it look tidy. Plus it's a cool project to just do in general so cost is entertainment with a bonus in a way 😀, subscribed from Australia so you can tell your Daughter you're internationally known now. 😉🤣🤣
if your grid goes down for over a week run the grid tie to main breaker box after you disconnect the main power line coming in/out from grid. I have a off grid setup. testing it over this winter before pulling the grid plug.
That's what I did for peace of mind when the grid goes down. Have a Bluetti AC300 that powers a few circuits, frig and office daily to keep cost down a little. But have battery power / solar when the grid goes down we can still keep warm powering the furnace.
I can see room for 20 Panels on the grid tie. My setup is a 12Kw one, 2/3 grid tied 1/3 Hybrid. It puts on average 1.2 Mwh per month to the grid, less when charging my EV. The Yearly True up only gives 3 to 4 c per Kwh wholesale rate. Do not expect the utilities to pay your system. Do expect to pay Zero if designed correctly.
I got a Bluetti AC300 and 2 B300 batteries for the exact same reason, I have a grid tied system and wanted to have the ability to keep power during an outage, other than running a generator all the time. Now I just need the panels to keep it charged, I do not have enough.
You could also just add battery backup to your grid tied system and you will have the same benefit for less money. You solar will still work when the grid is down and you have backup battery
@@DIYnerdman I see the benefit of adding storage to a grid-tied system if the inverter is a model that suppoers islanding in case of a blackout (hybrid can mean two different things, one is grid-tied with batteries that help you self-consume at the high priced hours, which can save you a lot of moeny but that still goes down with a blackout. The other kind of hybrid is the one with a transfer switch (maybe automatic transfer switch) to disconnect from the grid and work off-grid in case of a blackout, like some Sol-ARK models in the US. For backup, adding panels is a good idea, isolating critical loads is absolutely good but i would try to hook it up in a way that during a blackout I would be able to use ALL the solar panels, not only a few. Altogether you have something like 8kWp panels up there and when you need the most - in case of a longer blackout - you can only use a few of them. I had some correspondance with an expert because I want a system like this. In my country no islanding type of hybrid inverter is not approved, so he proposed I have two inverters. The grid-tied is the "main", in a conventional grid-tied setup, but have a battery bank with charge controller on the DC side. Then hook another one (maybe smaller) inverter on the batteries too, which is used when grid is down. The trick is how to use the batteries. I want to set them up to maximum 25% discharge to keep their life long and change that setting in a longer blackout to something like 75% (Lithium iron phosphate)
@@koborkutya7338sounds ok, but u dont need to be that soft on ur lifepo4 batteries, they will eventually die from calendar ageing anyhow, try and use a reasonable bit of ur power storage is best economy for this chemistry, 10-90% is not hard on lifepo4, I understand what u mean & extra storage for a rainy week etc, is always good too. Cheers
Good job, nice vid of ur system. I have 10kw of grid tied solar, but I use a 5kw AIO inverter as a charger for 5-6 hours a day from house GPO for now on timer & then onto battery from 3-4pm to 9am to run several fridges & TV’s, computer, microwave & water pump, which uses about 50-60% of 3 x 5kw server rack type batteries, so about 10kw mostly. I also put a 1800w element in my 320 ltr hot water system on a timer for 2 hrs/day presently, so if it is cloudy we still dont draw from the grid much if any at all and generally get about $30-$50 credit/month from our FIT and can use our air cons for hot or cold whenever we need to for extra comfort, having a large 320 ltr HW system is like having another 15kw of storage in hot water that will last a few days if something does go wrong, & we also have backup gas HW as extra redundancy. I covered a Skillion roof area, our main living areas, with PV panels, and the difference it made in cooling the whole house in summer was huge, just from the shading effect. I love it. Oh yeah, Sub’d & liked to help get ur daughter of ur case. Cheers
I've always wondered about these DIY systems. If you plan to move, what would you take and what would you leave? Leave the grid tie system and take the off grid system, leave it all, take it all?
Nice setup. I was wondering why you can't have the solar panels charging the delta pro constantly while off grid. Is it bad to have the pv connected the delta pros all the time?
Рік тому+1
By seeing your setup i got to think why additional panels when you can switch the existing panels to your setup. Saving the extra cost of adding more panels. The existing panels still produce power it's the inverter that cuts the power when the external grid goes down.
That is true! I have had that thought as well. I may make a video showing my solar production throughout the day and where there is typically excess power being produced from my grid tied system that could be used to charge the DPs. The truth is my system has changed a lot as I learn more. The problem is I learn a lot after I've already purchased and installed a part of the system. My grid tied system has microinverters on each panel so I'd need to think about how I could isolate this when the grid is down. Might be a big pain if I had to disconnect each microinverter to run the DC direct to the Delta Pros.
Рік тому
@@DIYnerdman in theory these microcontrollers could be on one bracket together and some sort of High power relays between them and the panels. Basically this means redoing All that's installed and introduce a custom switch relay board that needs approval for safety regulations. I think nobody has ever done this before but should be possible.
Do your Delta Pros manage the 10 circuits together or does the SHP use one DP then the other (in series). What happens if one DP drains the battery first? Thanks.
That is just enough power to run my kitchen stove but nothing else but I am getting 28 solar panels free from a friend there are 10 ft wide 18 ft long these massive solar panels and I only need baby for those to run my complete house my land probably big enough to hold all of those I'm going to take them all one of them are like give to a friend of mine cuz it's a water heater.
Hi great video give a 👍 if I have a delta 2 can I run my air fryer off it says on the fryer 2000w ? Waiting on my delta to be delivered say’s January 🙄
I don't know a lot about the Delta 2. I've pulled a lot of power with the Delta Pro, so I imagine if the Delta 2 specs say it will handle 2000 watts it probably will.
Hoping to pick your brains on this... I'm thinking about using your setup for my DPs, since I don't have a solar grid-tie system I want to maximize the solar input (1600W each DP) by connecting to 4 of the 400W panel. With this setup of 8 X 400W panels connecting to two DPs and set it to power the house through out the day. This should generate roughly 3.2Kwh X 5 hour = 16Khw per day. Do you think setting it this way makes sense to save electricity costs?
Do you have your DPs connected to your house through a smart home panel? What you propose should work. I have run a 1200 watt portable AC unit off the DP while connected to solar and it ran all day. I can say the DP fans were on high keeping it cool while passing all that power through. I imagine doing that all day everyday may be tough on the DPs.
@@DIYnerdman thanks for the quick reply. Yes, I will purchase the smart home panel for this setup. My plan is to ONLY load the 10 switches to rooms that doesn't require much power. I recently purchase the DPs and haven't gotten to testing it with solar panels. Do you think charging the DPs with solar while powering the house will cause issues down the road?
@@tuvo9791 I have no reason to think that running the DPs while charging will cause problems. It has just been my observation that running a portable AC unit while charging from solar (about 800 watts coming in) the DP fans were running on Hi. I recommend estimating the amount of power you think your 10 circuits will be pulling before you decide how many solar panels to purchase. I am using less panels now than I originally planned.
The limiting part of the Delta pro is your input voltage can not be greater than 150v Check your open circuit voltage on your panels. Mine are 31 volts so I can only run 4 in a string = 124vdc. Max solar input is 1600 watts.
You added one more...I hope you get enough subs so that your teenager daughter will stop making fun of you...Been There and Done That! ( Well Still Doing it anyway, LOL).

FOR THE BOOOYYYYSSS!!!!
Can you post a link to where you purchased the isolator switch? Thanks
I added a link to the video description.
I’m curious why you didn’t go with a higher power panels … like 400W for your ecoflow
The panels I have are enough power to fully charge the delta pro in a few hours. So no need in my case.
