Quote HistoryQuoted: silly question - are there battery systems that charge from the grid, but can serve as backup power and peak shaving? Most of the time, if folks build out a battery system like that, it charges/tops off during the day via Solar, then runs off storage at night. All you're doing is converting from something (Sun, plant power or some source power) to DC to store, then back to AC to use... With out Solar you're just looking at Batteries, Inverters, a BMS, accessories and labor (unless you DIY). Cost of room or place to store batts, To store any usable power that will last any amount of time, gets real spendy, real quick IMO... |

Quote HistoryQuoted: I have three inverters in parallel, each is fed with a 50 amp breaker and will automatically pull from the grid if the batteries are low or if the house needs more power than the inverters are rated for. They all operate independently of the grid, but if the grid is down I'm limited to 150 amps steady (300 amps for 30 seconds). I don't sell to the grid as I didn't pay an engineer to certify the system and I didn't want to be limited by the power company on how many panels I install. I would have had to buy a different inverter to sell to them which would have cost about $1k extra. In my case I wanted multiple inverters as that gives me redundancy. I can loose an inverter and still make 100 amps without issue. Educate me on parallel inverters, haven't looked into it. Are they physically interconnected to maintain phase synch? |

The curse of AR15.com. Get both.
I can type a wall of text, but an everything system can be very expensive. A minimal system can be much less so. We do have a whole house on a rental. It was picked out by a short sighted bean counter. So money was saved up front, but operation cost $/h is quite high. We do not have NG, so we are on propane. So that means about $150/day for electricity and a propane truck every 3 days. Ok for a rental, but almost useless for a hurricane. Diesel would probably cost less than 1/2 per hour to operate, plus diesel is more likely to be available after a hurricane. But that would have been 50% more expensive up front. For that 50%, we could have easily put in something similar to a powerwall. But a whole house battery is more an emergency feature at that price point. It would take multiple units to run central AC (just do to the current draw). Still I bet both could give you the best quality back up power, with the fastest transfer time and lowest operating costs. Ultimately it depends on draw and goals. Powering a few refrigerators and a mini-split is easy - a 4k sq foot house is another thing all together. --- FWIW, I have that EG4 system in storage right now. I wanted it for some offgrid buildings (I still need to get the buildings up - but I have 3 years for the tax credit). With a 15kwh battery, it is under $5k per 6kw inverter (that is under $4k for the 15kwh battery, and about $800 for the inverter/charger) - pretax. A $1k portable generator (sorry, I forget the size, but it was a large one - maybe 10=12kw) can charge it (hell, iirc at it's max charge rate for 2 linked systems). Since mine is for a business, there was a very good tax credit available. So add in a pallet of 400 watt solar panels - and the system with 12kwh of solar, 30kwh of lipo, and 12kw of inverter was about $7500 after tax. Mounting sold separately LOL. |

A powerwall is about $13k with the hookup box. It holds 13kwh of power and it uses lithium ion batteries.
My EG4 batteries aren't as pretty, but 5kwh of rack mount power is $1150. So about 30% of the cost. Not to mention they're LiFePO4 which gives many more cycles before they wear out and are less likely to have fire issues. |

IF you ramp it up to the same size battery, you are still 1/2 the cost of a power wall. Just a note - that EG4 does not have grid backfeed. The one with grid backfeed is a little larger (50% more capacity IIRC), and 4x the price. That said, it only gets depressing when you are thinking of having 4 of them on your house...

Quote HistoryQuoted: IF you ramp it up to the same size battery, you are still 1/2 the cost of a power wall. Currently I run my home on 35kwh of batteries and rarely run them down to 20% from cloudy weather. I expect I'll need more batteries in winter if I want to do full electric heat. Days are shorter and you need the most heat generation at night when it's coldest. ETA: That's correct, you need an inverter to use them as a battery backup (about $1450 per 50 amps of steady service). I know they have a couple wall mount models that can be placed outdoors. I don't think any of them have built in inverters. In most cases batteries make sense when adding whole home solar and you need to purchase the inverters anyways. |

Put in a 10K Generac and 100 amp transfer switch on NG last year, best friend is a master sparky, got it done for about 6600 all in.
Only large load I have is a 2 ton central A/C I put in last year, seems to start it easily. A/C panel says LRA is 41.7 amps, 10K makes 41.5 amps at 240v and the Generac document I found has the 9k with a surge output at 70 amps. My buddy has same genset and it starts his older 3 ton without issue. I can live with the central a/c if needed but it's started it up every time I've tested and in 1 short outage. As always YMMV. |

Quote HistoryQuoted: Yes. They talk with each other and maintain phase. I put a new subpanel in and wired my home to it. The old breaker box just feeds the inverters. I've been running off two inverters for a few months and ordered the third a few weeks a few weeks ago. Should have it up and running in the next week or so, just have to take an hour or two and do the final wiring. The third inverter will also let me add another 10kw of panels if I decide to. I don't need them now, but I want to expand my house and may add an EV at some point. I like the idea of having my own fuel generation at home. https://www.ar15.com/media/mediaFiles/57761/20240616_181206_jpg-3251345.JPG Quote HistoryQuoted: Quoted: Educate me on parallel inverters, haven't looked into it.

I did not read the whole thread but often systems I encountered required load shedding to qualify for automatic transfer. The generator sizing could not supply what was needed even for the reduced loads of a code load calculation to meet requirements for automatic transfer.

In the process of getting on now, just waiting on permits, I went with a 24kw generac air cooled. Wasn't sure if the liquid cooled was worth the $ as it's not going to run that often (I hope). And I probably could have gotten by with a 20kw, but 24kw was only a few hundred bucks more.
considering the trenching they will have to do to get the gas to the opposite side of the house and trenching for electrical (we aren't allowed to have exposed wires here, or conduit running outside of our house), installed price is 15k |

in 2017 when harvey hit down here, home generators were still a rarity, i knew everybody that had one and easily kept up with their fuel needs
after harvey a few new ones went in but very few after the big freeze down here i've been installing generators ever since, soooooooooooo many fucking generators are out there now. almost every new house has one or has a stub-up to put one in so if you're on propane make goddamned sure you've got enough storage for an extended outage. do not count on getting gas during an extended outage. most propane companies don't even have self-loading trucks so if there's no power they can't get even get it from storage onto their trucks |

I have a large portable job site honda generator I just wheel out and plug in when the power goes out here. I can run the well pump, some lights and keep the food cold. Good enough and not too expensive. I had to install a transfer switch and exterior plug. I also had to remove a small jumper wire on the Honda, because the GFCI on the generator didn't play well with the house.

Generac whole house, fully auto owner since 2007 in coastal Virginia. Runs like a champ, powers everything except dishwasher, dryer and hot tub. But best advice I can give is get a yearly service agreement with installer. We started with Southern States, in Deltaville. Our original installer comes out once a year for a full service…usually runs $160…systems self operates for 30 minutes weekly. Your respected service tech is your friend….don’t skimp on yearly maintenance!
It also helps that we only live one block from our fire department, so when Dominion Power fails, we get restored fairly quickly! |

When you lose power, just focus on the bare essentials. You don’t need/want to do a load of laundry with your power out. But in hot/humid places you do want your AC to work and anywhere wants the refrigerator to keep going. |

Quote HistoryQuoted: Quoted: Am currently running a 22 year old Kohler 45kw Lp gas 6 cyl ford engine,getting a bit long in the tooth.Going to upgrade soon for a Kohler 48kw 8 cyl engine. Seriously, that's a 250A panel running full bore 80% load. Wild, I couldn't even pull that much power from the grid with my 200A meter if I wanted to. Without EV charging I barely peak over 6kW even running AC in a 3500sqft house. With EV charging if I really very intentionally try to turn everything on I can hit maybe 12-14kW but you gotta work for it. I guess people need to run 500 tons of AC and electric pool heaters during a power outage, not for me. Gotta be a pretty impressive bill every month. I know some areas lose power a lot more and for a lot longer and have different needs, but for me for the occasional power outage we get maybe once or twice year that might last a day or two tops but usually no more than a few hours, I just use a manual interlock and standalone generator 120v 3600W. Easily runs all the fridges, TVs, and central furnace (NG) so long as you're selective what you run. Basically everything except for the AC and oven. Gas stove top, hot water, lights, etc, all good to go. |

I was listening to a southwest power pool meeting today. Dude was bitching that their 2025~26 models didn’t have enough dispatchable generation to cover peak load in their reliability models. They decided to flip some renewables to dispatchable and call it good. I have considered a generex but I figure during an outage the gas pressure will eventually give out. So I got a propane capable 4kw with a stash of propane.

Install wasn’t complicated at all, the only hard part was pulling the wires through the conduit. Definitely helps having a second set of hands.
Generac 24kw, Transfers witch, battery, and pad was $7,200 shipped to me. Included a 10 year warranty. Cost to run 850ft gas line and new meter install was $3,200. Electrical supplies around $500. Black iron pipe from meter to generator around $200. All in for about $11,100 doing all the work myself excluding new gas meter install. |

Yesterday got away from me. I have a 150A service that isn't getting upgraded. I currently have an Interlock kit and a Generac GP6500 portable. I usually keep enough gas to run it for about 48 hours. I typically will not run it at night. I also have two Eco Flow Delta 2. One is rock solid, and the other is getting ready for a warranty claim. 2.5T AC, Elec Water Heater, Gas Range, two fridges/ freezers, and a 350W average are always on electric devices. According to my Sense, my max peak continuous draw is around 20,000 W. That's with everything on AC, Dryer, Water Heater, Dishwasher, and charging the Jeep (PHEV).
I would love to do solar with a battery, but not at this home. I will look into a 22-24 KW generator with ATS. I would also love to install some power walls or similar for time-of-use load shedding. However, that would be a big jump in cost. |

I get by with a Yamaha 6300isde and a transfer switch, will run everything but the hvac.
I’d love to have a 1800rpm diesel whole house genny setup but can’t justify the costs. The generacs people are talking about are riding mower engines bolted to a generator and have terrible fuel economy, lp or ng. You are paying for the convenience and long term storage properties of those fuels. I lol at some of the prices posted. |

I own a lot of diesel equipment, these days fuel quality and long term storage is a serious issue. LP can sit for years with no degradation. It's really the ideal backup generator fuel source. If the genset were to run frequently I could see diesel but for residential emergency backup LP is the better choice, especially in cold climates. |
