@Chri5co63 I am going to set my CHINS to the parameters in post #23 because they look more realistic than the defaults and I will let you know what happens.
This is our setup with connections as shown (less the separate inverter and charge controller as we’ve replaced those with the on MrPow inverter charger…If all 12 panels are connected in series then amps =9.02a, voltage = 21.6v x 12=264v w=2381
But if I have interpreted what you have said above
If they are connected 6 strings of 2 in parallel=
2 in series =9.02a,voltage =2 x 21.6v=43.2v
then 6 in parallel =9.02 x 6= 54a, voltage =43.2v w=2332
In the listing above it suggests max charge amp from inverter to battery =02c =40a... 20% of a 200ah battery. Your peak solar pv output is 54a. at 43.2vdc available to the inverter
The following is a link for the manual for our PowMister Solar Charger.It seems to me that we are talking about AIO SRNE, this is a manufacturer, powmr brand
3KW SRNE Off-Grid Solar Inverter 24V HF2430U60-100 - SRNE Solar
Max.Voc:100V;Rated input voltage:110/120V HF Series is new hybrid solar charge inverter, which integrates PV charge &Grid(Generator) charge with AC sine wave output. Adopting DPS control algorithm, getting higher response speed, higher reliability and higher industrial standard.www.srnesolar.com
my version is 220 volt

it says here, the maximum current from the panels is 40 amperes
2s6p you get 54 amps which is more than 40 amps
maybe 3s4p is better for you
also note there is a maximum pv power parameter of 1600 watts, which is less than 2332 watts
Are your solar panels already connected?
i also want to go over 1600 watts, my panels are 595 watts in a 2s2p circuit i fit into 80 volts and 36 amps, 2380 watts

but i have feelings about it

I have exactly the same instruction, but on the side panel of the AIO there are these 1600 watts and 40 ampsThe following is a link for the manual for our PowMister Solar Charger.
One can find on pp. 31-32, the Technical Specifications. The listed Maximum Input Current is 60A and the PV Charging Current Range is 0-60A
Aha. Nice article! In another...

What Does Solar “Inverter Clipping” Mean?
November 2, 2017
The short answer is that “inverter clipping” means your solar inverter is limiting slightly the amount of electricity going from your solar energy system into your household for use, because it reached its maximum capacity.
Here’s a longer explanation.
For background you should know that, like solar panel ratings, inverter ratings are approximate. Many inverters can convert more DC power (from your panels) to AC (for use in your home or business) than their model numbers imply. For example, the maximum power output of the SolarEdge SE7600A is actually 8,350 watts, according to the manufacturer. So the inverter has no problem handling up to 8,350 watts of capacity at a time.
If the panels are operating at a capacity that exceeds the inverter’s capacity, “clipping” occurs. The inverter trims the output to the maximum it can handle and you lose a little production. This graph shows a customer’s production with clipping at the top of the curve.
Reference above "clipping" If the panel output is greater than the inverter spec......
Yes, the solar panels have been connected since last summer. We connected them according to the Eco-Worthy Kit setup instructions.It seems to me that we are talking about AIO SRNE, this is a manufacturer, powmr brand

that's exactly my goalor very high efficiency year-round with occasional clipping
1600/2400 turns out 50% but is fully invested in the parameters for both current and voltageI don't think it overly matters if the panels give out a little more than the inverter is rated at ,,,, possibly up to 20% but it is important you are aware of it. Especially If like in the Uk there is little chance of achieving maximum solar output.
The system has been up and running (charging 4 12v Lead Acid Gel batteries connected in 2S/2P for 24v) since las summer. At this time, we are only replacing the batteries with 4 Chins LiFePo4 12v 200AH batteries connected in 2S/2P for 24v.I have exactly the same instruction, but on the side panel of the AIO there are these 1600 watts and 40 amps
can you take a photo sticker of your AIO's specs?
do you already have everything working? and you want to change only the battery or the system is just planned?
what are parameters 04 and 05i plan to do the following settings for lifepo4 140 ah 24 voltss battery
04 26 (3,25) v
05 26,4 (3,3) v
07 40 amper
08 USE
09 Boost charge - 27,6 (3,45) v
10 Boost charge time - 120 min
11 Floating charge - 27,6 (3,45) v
12 Over discharge voltage - 24 (3) v
13 Over discharge time - 30 sec
14 Under voltage alarm - 24,8 (3,1) v
15 Discharge limit - 24,4 (3,05) v
17 Equalization voltage - 27,6(3,45) v
28 Max AC charger current - 10 amper
35 Undervoltage recovery - 25,6 (3,2) v
36 Max PV charger current - 40 amper
37 fully charged recovery - 26,8 (3,35) v
my goal is to use the battery as little as possible, during normal times, to save it during city grid outages
what are parameters 04 and 05
04 | Battery Power to Utility Setpoint | 23.0V (Default) | Setting voltage point back to utility source when selecting “SBU” in Program {01}. When the voltage of the battery is lower than this setting, the output switches from inverting to the utility (generator). The setting range is from 22c – 26-v in 0.2v increments. |
05 | Utility to Battery Power Setpoint | {05} 28.0v (Default) | Setting voltage point back to battery mode when selecting “SBU” in Program {01}. When the battery voltage is higher than the setting value, the output is switched from the utility to the battery mode. The setting range is 24V – 30V, in 0.2V increments * Cannot be higher than setting in {14} |
The CHINS Inverter started doing weird things so I set it back to where it was. It appears that my batteries, TCBWorth, don't like those settings. I have tried to get the parameter info from them but got no response.
Like I said previously, I am impressed and grateful with the correspondence from Chins. Not so much with PowMr, as the only response I received was to set the Battery Type as "User". Big Deal ?The CHINS Inverter started doing weird things so I set it back to where it was. It appears that my batteries, TCBWorth, don't like those settings.
