Does Adding More Batteries Increase Inverter Output Performance? Adding 2nd Eg4 Wallmount Battery

[@donaldhoudek2889]

As mentioned before, add a soft start unit. I went from an inrush of 94 Amps to 24 Amps with a continuous draw of 18 Amps. There is no dimming as there was before. You may even get the company to send you one to review on your off grid setup.

[@diySolarPowerFunWithRay]

I think that would definitely work!! However, I like having a high surge for these inverters. :)

[@adon8672]

​@@diySolarPowerFunWithRayWhy?

[@diySolarPowerFunWithRay]

haha. Yeah :)

[@DJLsbVapes]

I am very confident that your wires supplying the house are undersized, higher inductance with high resistance, yeah, lights will flicker.

more volts less amps, why 220v rules

[@diySolarPowerFunWithRay]

Thanks!! This may be the cause of the dimming. I may try this if I have time before I install the new unit.

This is the video where where install the 2nd inverter and explain my decision in selecting that wire: kzbin.info/www/bejne/pnOumWV4odihqM0si=A5ZpkK9oGZVSAfXd

[@davebenson4114]

look into a soft start for your compressor.

[@Everyday_Foreman]

It looks like the wires going from your inverter to your panel is undersized for the load that you are seeing. There is the issue of soft start with the air conditioner. You can also get a "run capacitor" as well and a "start capacitor" that will reduce the current to the compressor

[@diySolarPowerFunWithRay]

This is the video where where install the 2nd inverter and explain my decision in selecting that wire: kzbin.info/www/bejne/pnOumWV4odihqM0si=A5ZpkK9oGZVSAfXd. I didn't account for a 90 amp spike.

[@jerryguerrero4354]

The question I have concerning your lights dimming when your AC kicks in is. Does that affect your appliances? I'm assuming that's a slight dip of power, is that a concern?

[@MarcosViloria]

Q? did you change your batt DC discharge settings to double the amount you had before you installed the 2nd Batt? Otherwise your inverter will limit your surge capacity to only 125A DC instead of 250-280 DC

[@diySolarPowerFunWithRay]

Good catch. Yeah I updated that earlier. Forgot to mention that I had updated that in the video. I think that helped reduce the dimming when I made that change earlier.

[@MOKPT3]

Could be the lighting, but looks like your 6000xp air filters could use a cleaning. It would be interesting to see what a soft starter would do to the flicker. Also the wires going to the main box seem a bit undersized, but it could be because they are beside the monster EG4 cables. Thank you for the video. I have 1 6000XP and 2 EG4 wall batteries. I really like the capacity.

[@vevenaneathna]

the dimming is variable based on where in the ac waveform the ac is turning on. if you were able to have the ac turn on exactly at the zero point every time, i doubt there would be any dimming. this is one of those issues with led lights and power factor if i understand correctly. im not a fan of ac soft starts. ive heard from hvac people that they can cause issues with air con longevity. seems to me like it would be the opposite tbh, but my main issue is their price, durability, and the parasitic load the place on the house. appearently you can phase shift when the AC can turn on to the zero crossing point of the ac waveform everytime reliably by attaching the airconditioning through a solid state relay. solid state relays do have some loss but not very much. i believe its only when the circuit is in use. solid state relays are basically a box with a led and solar detector which opens a switch. because the light producing element can only turn on at the zero crossing point of the wave form, it almost perfectly syncs the closing of the switch with the zero cross point of the wave form. because the power delivered is the dot product of the instantanious ac voltage, the actual starting current requested will essentially be 100amps (or whatever your unit draws) x 0 volts, and will then gradually ramp up to full following a sine curve, i think ~1/240th of a second later, but thats all the electronics in the inverter needs to properly match the load. worth a shot. i dont have formal ee training whatsoever. i think solid state relays are only a couple of dollars. better than a soft start imo.

[@jefflucas_life]

what you didn’t add a soft starter yet and you did this what da?????

[@kentuckycornbread8502]

It’s always fun to see solar testing. I have a question unrelated to this particular video. I have a metal built “amish building”. It already has a slanted metal roof and I was going to install regular size solar panels across the top. I really don’t want to drill any mounting holes that may introduce future leaks. Do you know of any magnetic mounts for 100W/200W solar panels? I been looking at earth magnets with holes already in them and maybe attach them that way to the panel.

[@diySolarPowerFunWithRay]

Very interesting... Sorry I don't know of any non drilling options. Please let me know if you find something you like though

[@archersacres462]

One quick thought I had when watching (not at all an expert just to be clear), is the gauge wire running from your setup to your panel a little small. Hard to tell what gauge it is from a video. Just wondering if the gauge is too small especially with 91 amps. Not an electrician, just a question/ thought

[@diySolarPowerFunWithRay]

Thanks... here's the video where I installed that and explain my wire size selection. 👍 kzbin.info/www/bejne/pnOumWV4odihqM0

[@TheSnowbo83]

Thought the same thing. I'll check out the video.....

[@GavinStoneDIY]

Good video. I think that gray cable you used between batteries is for the inverter paralleling. It has a specific pinout. Did that work for communication?

[@diySolarPowerFunWithRay]

Thanks.. that's Interesting. I thought it was for battery paralleling. I'm seeing 2 batteries and 560Ah in the eg4 app now.... So it appears to be working fine.

[@GavinStoneDIY]

@ the battery parallel coms cables are typically green. But shoot, if it works it works.

[@PazLeBon]

need to move house soon for more wallspace

[@tech-test-break-fix]

Changing over to mini split ac units would add tremendous value to your system

[@diySolarPowerFunWithRay]

Yeah, I think I'll add one soon... hopefully. Thanks

[@TheSnowbo83]

Have you ever thought about getting an eg4 mini split solar to supplement?

[@diySolarPowerFunWithRay]

Yes, I want to get one of those for my front room.

[@Solar_and_Security]

Nice video as always Ray.

[@CarstenDressler]

Would love to see a video on the firmware updates for this battery

[@diySolarPowerFunWithRay]

I'll see if I can make a short for if or when I need to update the firmware.

[@mrplay6294]

Its a common thing that will happen with split cap compressors... i have a 200 amp service and my lights flicker.. either add a soft start or update ur ac system with a inverter drive conpressor if it bothers you that much for half a second.. my units 27 yrs old been doing it since day one. Unit has just a normal run cap no start cap and works fine

[@mrplay6294]

Just another tip anything you add onto ur unit will void any warranty if you show or tell ur hvac guy or the oem you add3d extra parts on their unit it wqsnt designed to run.

[@mwolrich]

The wires from the inverters to the panel appear to be undersized, to start with…. Increase the gauge of those, first. Next look into getting a soft start kit for your AC, which will vastly reduce the starting current required. Problem solved, AC starts quickly, lights no longer dimming 👍

[@RobertsIslandLivingAdventures]

Maybe a capacitor?

[@johnpeter366]

I've been hoping you would make a video on the new panels and inverter and what affect it has on your monthly bill

[@diySolarPowerFunWithRay]

Haven't pulled anything from the grid the last 3 days... but cloudy winter days are coming.

[@diySolarPowerFunWithRay]

Since summer is over and I'm going to be testing new inverters I'm not sure how I'll have enough data to provide a good overview of cost savings.. hopefully in the winter I'll have some data to share and also this coming summer

Doesn't really bother me. Let me get one more pack. Great work by the way

[@unijabnx2000]

Whats interesting is the ecoflow DPU says it can start an AC unit if the LRA is lower than 120Amps... buts its only a 7200w inverter... I bet the lights would still dim tho, I know mine do when it starts my 3 ton heat pump.

[@JR-xw5dk]

@diySolarPowerFunWithRay You get line balancing and the extra AC power when you have solar. $1600 or so more. I wonder if you could exchange it or sell the 12000xp

[@sh839c]

Seems normal

[@flyingaz]

I have 3 x 6000xp's and 4 x Indoor WallMounts that have been running my house in AZ for the last 2.5 months. Even with EasyStart soft starts on each of my 2 x 3 ton Trane A/C's (old, from 1995) (soft starts dropped their inrush from ~100A to ~26A), I still get a flicker each time they start. Otherwise has been working flawlessly. But the flicker does really bother me, too, ha.

[@PazLeBon]

must be messy, why not fewer bigger units?

[@flyingaz]

@@PazLeBon Not too messy. It's setup on a 10' long 12" wireway with emt stubs from the inverters. So no visible wiring and all protected. It does take up a lot of wallspace, though, yeah. I had considered going with 2 x 18kpv's, but since I didn't need the grid interactive stuff, went with the 6000xp's just to save a few bucks. But, if the 12000xp's were out back when I bought them, I'm pretty sure I would've gotten two of those instead, yeah.

[@PazLeBon]

@@flyingaz yeah fairplay, spose many folk upgraded bit by bit too. maybe the makers should part exchange more, trade in a 6k when you buy a 12k kinda thing

[@diySolarPowerFunWithRay]

Someone brought this to my attention. To reduce or eliminate the dimming you could try this is the app: Settings -> Discharge Setting -> Discharge Limit(Try increasing this value).

[@flyingaz]

@@PazLeBon That would be sweet. I would definitely be tempted to upgrade to the 12000's if they had a nice trade in deal. Probably be tempted to upgrade every time a newer, better one came out though, so maybe better they didn't. Ha

[@quickquote1568]

Luxpower inverters still use low-cost, high-frequency, transformerless inverter technology that was originally used in cheap inverters from the 80s. It offers no galvanic isolation, and a shorter life expectancy and can damage your AC appliances or fry your EV's onboard charger during a catastrophic failure of its H-Bridge circuit. I would never connect any of my household appliances, especially my EV, to one of these high-frequency inverters. No Thanks.

[@diySolarPowerFunWithRay]

The majority of the solar industry is choosing to go the Transformerless route... they also have us testing certifications that consider them safe.

[@user-ei3ml8jo1s]

@@diySolarPowerFunWithRay not true. Companies that sell cheap chinese inverters you HF mosfet designs. When they fail, and they will fail, the failure mode is not graceful. Victron for off grid only., Schneider for on grid or off grid.

[@HybridShedIraq]

By the way there is no issue with connecting 95% battery with 15% battery.

[@johnhelms]

Just add a soft start for heating and air. It won't pull so much power and won't dim your lights.
