Always enjoy watching your videos. Very informative. We've been wanting to incorporate a battery backup in our new construction and after living through 3 days of power outage and running extension cords from our generator to the fridge/freezers, I'm even more convinced. I like how you provide the Kw/h info but for the less technically inclined, it would be cool if you did a video on how big a system needs to be (ie how much kw/h) we need to keep the main systems (lights, fridges, water pump for well, etc) up and running and how much kw/h would be needed per day. i realize every home will vary but I'm hoping there's an average we can go by. Keep your videos coming! Love them.

@myvids4329 2 года назад

How far north are you? Here in NH my array produces about 4X more energy in June that it does in the dead of winter, its a big difference. We have net metering so I sized it to generate credits in the summer that I could spend in the winter and be mostly neutral, maybe a little positive over the whole year. Its a fairly big system at 12kW but its not optimally placed. Still, these new generation of panels really produce a lot of juice so I think you could definitely brute force it depending on how far north you are

@trueriver1950 Год назад

@@JaiHenwood that's harder than you think. The issue is that you can't have the system go from off grid to on grid automatically as the phase of the inverter will not match the phase of the grid supply. That's why the most common on grid set up is unusable when the grid connection goes down -- counter intuitive as that sounds. A manual changeover in both directions is probably the best you can do. There are also legal implications in some countries, to protect the grid from rogue solar when it comes back on after an outage. That means that any design Will suggests may not be legal in any other country. Take local advice.

@roykaplan 2 года назад

I can understand the benefit of connecting the main connections to the batteries on a diagonal when not using a bus bar, i.e. when jumpering from one battery to the next, as each connection adds resistance to the circuit. But surely the resistance across the buss bar must be minimal with negligible current loss over its length (1m?), and if so, connecting the main cables to the same side (top or bottom) of the bus bars will have no real-world negative effect on the batteries.

@stefanvanzyl9090 2 года назад

Will did a video on exactly this a few weeks ago, and the result was visible and measurable.

@roykaplan 2 года назад

@@stefanvanzyl9090 Do you mean the Current Sharing videos? Yes, there was a large difference because the batteries were interconnected to each other with jumpers. Each connection adds to the resistance and thus the last battery would suffer if the connections were not diagonal. However, when using a bus bar you are not adding the resistance of all the connections as each battery is directly connected to the bar. Instead, the only difference in current flowing to each battery is the resistance of the copper bus bar itself (which is near zero).

@stefanvanzyl9090 2 года назад

@@roykaplan the resistance of copper is always the same per unit area of conductor thickness. whether you have a 1awg cable or busbar with the same thickness, the resistance is the same, and it's never near zero. Even 0.1% equivalent resistance will still result in the first battery being "prioritized" or drained first.

@roykaplan 2 года назад

@@stefanvanzyl9090 I just checked, the resistance of 1awg copper cable is 0.126 ohms per 1000 feet at room temperature. That translates to about 0.0004 ohms resistance across the one meter bus bar. At these currents that's pretty negligible. You will have more resistance variance at each connection screw terminal.

Great video thanks. Question. When you pre-charge the capacitors to avoid the spark. Why can’t you just turn off the battery breaker when you attach the batteries to the inverter.

@stefanvanzyl9090 2 года назад

These batteries have the pre-charge function built-in already, no need to use an external resistor (which must still be used for other batteries) Turning off the breaker means that you're just going to hide the arcing inside the breaker when you turn it on again, this defeats the purpose and can still damage your inverter

@turbokatzenburg5732 2 года назад

The NEC (National Electrical Code in the U.S.) has full information on how to do proper load calculations (which incorporate good safety margins) to determine real-world ACTUAL load demands for an electrical service. There are also several on line load calculators that are excellent. You will need to know square footage of your house/shop, amperage (multiply the current times voltage to get wattage) or wattage draws of ALL appliances and heating/air conditioning equipment, etc. and also current draw on other unusual loads like ev car chargers, well pumps, and so on. Most also ask for data on location and climate to account for heating and cooling average costs. Take the results of the load calculator, add 10 percent and the result in total watts divided by 1,000 will be the inverter capacity minimum size. (Round UP if necessary to the closest available size, NEVER round DOWN.) Example: load calculator total is 13, 450 watts. Divide by 1,000 gives 13.45kw. Inverter would be 15kw single unit or 3 stacked 6kw units. Higher is always ok, but never go lower than the calculated value or you will get system shutdowns at heavier usage.

@myvids4329 2 года назад

Look at your power bill. Pick the worst one and add a safety factor if you want to be totally off grid while keeping in mind that winter at northern latitudes is brutal for solar. If you will remain on grid you should size it based on your budget while concentrating on solar over batteries since those will provide the most bang for your buck, especially if you live in a net metering state or a hot state with lots of AC use.

I would like to run two full size refrigerators a 7cf deep freeze and a commercial sized kegerator in my garage could I get by with one all in one unit and a couple of these batteries? And how much solar input do you recommend? Thx

Been waiting on this one!

I would like to have a all in one inverter that I can plug my 24v 3100w solararray in and not use the Ac hookup. Can you tell me what I need?

What do you do with the old equipment you tear down when you build new systems?

What if you wanted three phase? I have a cnc mill, that I would love to go solar with.

Now how about this, my batteries are installed following the original rack configuration, both positive and negative are connected on top of the bus bars, not on a diagonal configuration. How do I disconnect everything safely in order to flip the negative bus bar upside down? Thanks!

I have a setup but with different batteries

I didn't get from the video whether the EG4 has an inbuilt precharge circuit / inrush limiter? Or does the BMS they use have one? The batteries not outputting the same current make me lean towards building a 30kWh 2p16s configuration to avoid having to deal with the shenanigans of parallel batteries. It's also cheaper :)

What would be the typical location in a house to install? Garage? Would ambient heat be an issue in an unconditioned, uninsulated garage in California? What would one do if the garage is ideal to install but the ambient air is over 113?

Is there an rack mount UPS that can leverage one of these in a rack to power servers and networking requirement? The current ones are so expensive. Well over $1500

@timhall5226 2 года назад

Will, can you please add some information regarding potential use as an UPS? I am concerned about this system if it is as I understood you to comment that it will burn about 75 watts of energy 24/7. Is that correct? Where I am located I have minimal solar exposure and it is a concern. Where I live is also one of PG&E's favorite locations to shut power off during any minimal weather event. I just purchased 3 of the EG4s along with the rack and am looking for the best options given my situation.

75W per inverter -- 150W since there are two

Can you hookup a generator to charge the batteries as a backup if there are multiple days of rain? Would it be better to just power the house off the generator?

I want to put one of these systems in my Skoolie... do those batteries have high and low temp cut offs?

Hoping that you still read older comments! I bought two 24v EG4 LiFe PO4 batteries and was wondering why the wires connecting to the busbars were smaller than the wires leaving the busbar to connect to the Lynx Distributor. How do I know how to size the wires running in parallel?

@coltybambam Год назад

+1 would love to know more about a two battery configuration, and wiring sizing. @Triston, did you figure it out?

@tristanl456 Год назад

@@coltybambam I did! So, the reason that the wiring going from Battery -> Busbar is smaller than Busbar -> System is because the power draw from each battery is relative to how many batteries you have. Say you have a system that draws 300a total at 24v. You'd need a minimum Wire Gauge of 2/0 which can handle all 300a of power draw. This 2/0 cable is what would be from busbar -> system. However, because you have two batteries, the power draw is divided equally between each battery, meaning each would only be 150a. This means that from batter -> busbar, you can have thinner wire (in this case, 2AWG) because there would (or should) never be 300a running through a single battery's wire at any point. This logic expands to any amount of batteries. If you have 4 batteries, then battery -> busbar only needs 6AWG minimum because each individual battery is only providing 75a
