Voc definetly not in fact for panel Voc at 25°C you must compensate for every°C below 25° by 0.3% eg. VOC +7.5%@0°C ,as for every degree below 25°C the Voc will rise with 0.3%. Maximum controller current is not that crucial as the controller will limit the current(clipping) but also try and stick to the manufacturer specs it is there for a reason. VMP X IMP = Panel wattage.

You are correct, you can never have enough panels. As long as you do not exceed the voltage limit of your MPPT, you can have as much panels as you want and don't let anyone tell you otherwise. The inverter will only draw the current which is within its limit, from the panels and clip off the rest, so you can safely ignore the max power of the solar array. For example, if you have 5kw inverter, MPPT operating Voltages range 120v to 400v, and max current 13A.  If you keep your string voltage below 400v, you can have 20 x 415w JA solar PV panels installed in 10s2p giving you operating voltage of 367v and max potential current of 22A but your inverter will only take 13A. Your potential/theoretical available power is 8300w and the only thing you will burn is your pockets. 
Will I do this, NO! it will be a total waste. will it work, 100% sure it will work 

This is an informative article about oversizing the PV Array. It also includes the important footnotes of what has to be avoided.

"................The most important input characteristic which should NEVER be exceeded for any SMA inverter is the input voltage limit. Inverters and their constituent components are designed and rated for certain input voltage levels. If an input voltage were to exceed this rating, it will almost certainly result in the inverter's immediate failure..................."

I have been reading up about solar panel efficiency and i would like to raise a question. I do understand that mppt charge controllers has certain specifications and limitations. So for argument sake a charge contoller has a limit of 100v and a max pv input of say 1500w. So my understanding is that your panels collective voltage cannot exceed 100v and the max power of the solar array cannot exceed 1500w. Here is where my question comes in. If solar panels have an efficiency of between 15-20% it stands to reason that you will never have a scenario where your panels are outputting 100% of their rated watt. So in theory one should be able to add additional panels to your array without being concerned about damaging your equipment as long as your voltage stays within the controllers limit. Is my thinking correct or not?

Yes and no.
 
The voltage is definitely something you do not want to exceed as this could lead to permanent damage.
The watts, well it depends on the inverter. Some will simply clip amps to keep within the limits, others may trip / turn off the inverter until the watts reduce a bit. There may be some inverters which are damaged by the watt limit being exceeded, I am not sure.
 
Generally inverters will allow for more Watts from your panels then the inverter is capable of. ie the Luxpower SNA5000 is a 5KW inverter but can accept 6200W of PV (both MPPTs combined that is).

Don't be confused about panel rating in watts and efficiency of the panel. Your solar array will be sized according to your inverter charge controller and both voltage and current should not be exceeded especially not the dc input voltage. The panel is tested at STC( standard test conditions)  25°C@1000w/m². Let's take a 400w panel with a 20% -21% efficiency as an example. Most 400-watt solar panels have an efficiency rating of approximately 20% – 21%. This means that for every 1 square meter of solar panel hit by 1,000W of sunlight, between 200-210 watts will be converted into usable electricity. Diffrent climates and conditions can affect this number, but it’s a good estimate to use when comparing setups.

Thankyou so much. As soon as i changed to the settings that you recommended the alarm disappeared and the red light stop flashing. I have been struggling with this for the last 3 days. So glad someone could help me.

You havent mentioned what make of battey you have. Those inverters are actually quite smart as they pickup your cell configuration as being incorrect hence the error. Try changing your settings to LF08 which indicates 8 strings and needs a constant charge voltage of 28.4v. Your lipo cell configuration is most likely connected 2s2p hence wont work on LF07/09.

You are welcome. Glad to be of assistance.

I cant believe that actually worked. Thanks a million. My logger is online and i can now see all the data.

This is a common problem with the datalogger. Its a directional logger and not omnidirectional. I would suggest that you point the logger in the direction of your modem and restart it. Give it about 5 minutes and that should solve your problem.

Hope this is the correct place to announce myself.

If i wanted to know something specific, is there a certain section that i need to ask in.

Yes. Under the forum tab you will find subsections where users asks questions that are relevant to their queries. You will find listings as an example for Solar or batteries etc. You just need to learn to navigate the website. Just take your time and peruse through the different sections. You will get the hang of it.

Welcome. You are in the right place.
