Yeah that ripple frequency is between 2 and 2.5 minutes so I doubt it’s something caused by the inverter (which is why I find that wave so interesting).
The charge controller is in fact in bulk mode and charging as hard as it can. I believe at the time of the graph - it’s about 20a in and 90a...
Welll - left to right is time, and the orange line is voltage. I will have to look when I get back from vacation but I believe the voltage delta is about 0.2 volts
I was posting more for anyone that might recognize that pattern that seems pretty neat (but odd), and they could chime in as to...
Has anyone noticed their LiFePO4 voltage acting like in the attached image? This is while using about 4.5kW from my 16kWh bank, using Ampinvt 5000/15000w pure sine wave inverter. The voltage range is so small that I can't really see this pattern using any other method. The graph below is...
Don't feel bad! I'm glad you replied!
I connect all 16 of my cells together in parallel for a couple days prior to connecting in series for my 48v system. I think the Daly will do the job, as they are (at least as of right now) extremely close in SoC as far as I can tell from charging and...
Thanks! Any personal advice if I should seek a personal tax person to file my return, or doing H&R Block online has options for entering costs for the solar system?
Does anyone know if I qualify for and tax credit or anything like that for my expenses involved with building my off-grid system?
I'm running a 6500W residential roof-mounted system that I decided not to grid-tie, but instead run most of my upstairs appliances (2 * home office, 2 * AC units)...
Hi all - I am waiting on my 16 * 3.2V 310Ah cells (for a 51.2v bank) to be delivered, so I'm doing some research in the meantime.
My main question is basically - how well does the Daly BMS work to actively top balance the cells when in use?
My plan was to initially (and maybe once or twice a...
Small world - I live right where Liberia turns into Lomond. Thanks for the info - I'll keep an eye out on local possibilities before ordering semi-local.
Yeah I was going to ask if Ali was an okay site to order from. I know prices do not include shipping, but even with the shipping quotes I received, I was still getting anywhere from 7-8Wh/$ which is awesome.
I am in Northern VA (zip code 20110) if anyone knows of any local panel deals! Right...
Okay I've decided I'm going to go ahead and just build my final build from the start lol. Here's what I'm thinking:
Something around the range of 360w panel. I haven't decided on a panel, so I'm just using this for numbers guestimate...
Thanks for the replies....yup I realized that I meant pure sine, not modified....got that bit corrected.
And I figured that 100w 12v is the "standard" for panels....I was way off! Can anyone recommend a couple good brands/panel configurations that they have used and liked?
I figure that with...
To answer a few questions...I don't plan on making back all my investment. This is more just a learning experience and maybe a "feel good" factor of pulling 1kWh or whatever per day out of the sky.
I know I have much more to learn, but it seems as I expand out from 8 * 100w panels to as much...
