Thanks for your insights! ?
When I bought the system last year, I was naturally thinking that if I had 7.2kWh of stored power, I could use it all. Only after reading on many forums and websites that I started seeing "don't go below 30% or even 50% or your batteries will self-destruct!" ?
Of...
Great, thanks for confirming. I will then stay with what I have and not try to "improve" it further (I tend to do that :))
One aspect of my system I did not mention yet, because it had no impact; this is a kit I bought that includes a 12V 1500W inverter (used at 1000W for efficiency and within...
For me, it's a Chevy Bolt EV and I'm in Canada. The company I bought the kit from, has something for the Leaf but I understand that for 240V/50Hz, these kits would probably not be directly usable. I already had an LPG fireplace in the house, with the large tank so I can use that for heat but I'm...
Based on my battery specs (WindyNation), there wouldn't be any real capacity loss between 100% and 50% DoD. ?
Only going to 30% DoD would yield a higher lifetime capacity down to 60%:
100Ah, 100% DoD, 250 cycles = 25000Ah
100Ah, 50% DoD, 500 cycles = 25000Ah
100Ah, 30% DoD, 1300 cycles =...
Exactly! The car's 12V system is capable of supplying up to 1600W until it starts discharging the battery, that's why I had the charger derated to 26A so it wouldn't draw much more than 1000W.
Thanks all for your responses!
I'm already using 12/2 romex (not lumex, sorry) wouldn't that make the problem even more apparent?
The 26amps is at 24volts so this only amounts to 8.5amps at 120volts.
The only extension cord I use is from the car to the wall closest to the house (about 25')...
Thanks for the link, I will read it.
I've already been in touch with the supplier of the complete kit (evextend) and he's confirmed that this can be an issue that some get. We're looking into replacing and/or upgrading the inverter to avoid this issue. I don't really want to get a smaller...
Hi all,
I have a basic understanding of electricity (volts, watts amps, etc) but I need your help in solving an issue I don't understand.
I bought a kit from evextend.com that includes a split-phase 24v inverter in the basement with 6 x 12v 100Ah AGM (2S3P) batteries. It also comes with a...
I pulled out my trusty Kill-A-Watt meter and compared the stats between the hair dryer which pulls 1250W and has a PF of 1.0 which means it pulls 1250VA. I connected it then to the 24V/26A charger topping up the split-phase inverter batteries (supplying no load since I didn't want to switch the...
Interesting, I was told to set the charging rate to 80A (c0.27) the inverter/charger's max, which seems to be marginally too high. I could dial it down a bit for longevity's sake.
Of course, the only advantage to recharging quickly is to be ready for another outage shortly after the first one...
I'll double check but I'm fairly certain the cord has the right polarity all the way through.
The .6PF and strong/not too long cord is what I'm thinking too. I read somewhere (here?) that an inverter may be rated at 1500w but it really is able to supply 1500va. If that's the case, I'm asking...
If that's the case, I'm wondering if even increasing the inverter capacity might not cut it..?
Certainly looks like some sort of edge case. Just change a small parameter and it works or not.
I swapped my 0.6PF 1000w charger with a 1.0PF 1300w hair drier and all is fine too.
Hi, another newbie here.
I have a power backup system (no solar) using a 24vdc 6kW split-phase inverter charger and 6 x 100Ah 12v AGM batteries.
The batteries are currently connected using short 4/0 cables in between each battery post. The connections to the inverter are diagonal (farthest [+]...
Hi, I have a (non-solar powered) 6kW split-phase inverter used for power outages, only recharged by the mains power.
My battery setup is 6 x 100Ah AGM (2s3p) (24V) with 4/0 cables going parallel in between each pair of batteries and only 3 short 4/0 cables connecting each battery in the series...
Well, the manufacturer detuned it for me (Schauer) so I don't know if it's a potentiometer inside or if it's some firmware reprogramming.
The car inverter (true sinewave Windy Nation) does have a digital readout for watts and there is no difference between the two (950-1050). I did have the 26A...
Yeah, I figured I might not be reading that last chart correctly. There is this one but I have a hard time making some sense out of it ?
Too many lines and too many scales! I do have a clamp ammeter but it's only for AC and besides, my 4/0 cables are too short and too close to the batteries to...
