Hi Mark, yes imagine that I should try that by leaving them on charge for a day or so. Unfortunately don't have a BMV 700/2. During winter and Spring the panels easily charged the batteries, didn't had any issues, only now in summer.

According to the graph we started out quite cloudy yesterday but had some good sunshine between 11AM and 1PM and became overcast again. Not sure about the day before. Before December I had peaks of up to 1100W's input from the 3 x 305W panels. I still measured 119V input from the panels at 5PM yesterday... I'm a bit frustrated at this stage as I am worried that my batteries are not at their best at the moment. The cost me a arm and

Morning all Well, I did the following: Adjusted Bulk charge voltage to: 57.6V Float Voltage to 54V, when I got home batteries were almost fully charged, even on utility power no Amps were drawn by the batteries. I left them in that state for a couple of hours. Still during the night with 180W load, the inverter came on every hour as the batteries reached 47V. Before December the system was able to just about run through the night on a single charge. These are 4 x 200AHr batteries that are not even a year old. Is it still possible that they were not fully charged? With the 3 x 305W panels I only reached a maximum of 688W yesterday. I also think that the tilt angle on the panels is the biggest problem and not that the panels are dirty. The panels are installed on the second story roof and there is not a lot of space around them to maneuver and work. I'll be having a look at some bracket that can adjust the angle.

Chris, thank you very much for all your advise and help. I would have a look tonight and see that all my settings are correct. I have to say that we had a lot of cloudy days since December. Really hope that it would rather be the fault than anything else. I would keep you updated.

If I remember correctly the system goes back to Solar/ Battery at 54Volts. I assume from your :" I fear you batteries may have been chronically undercharged" that i might have damaged the batteries? Is my DOD correct? I used 47V to save some cycles. Should the mains power not fully charge the batteries? I cannot work out why my cycles are so short all of a sudden. I used the Axpert WatchPower to set up the Inverter. Yes, as soon as the Solar detects sunlight it switches over to Solar Panel charging (Solar first). System is at 70-80% late afternoon. Middle LED - yes, during daytime yes, but only short stints when on Mains/ Utility.

Hi Chris Some more info: 5kVA Axpert Inverter SCC? Max PV charge A= 20A, Float Voltage 54 Max Voltage 56.4. Return to mains on 47V Data sheet attached. 6FM200-X.pdf

I have not washed them since they were installed. They are on the roof of the double story and quite difficult to get to. More than one person have suggested that I should wash them, so would be doing that soonest and keep you guys updated if it made any difference.

Good day, please assist me with the following: Background: System installed December 2015, monitoring software installed April 2016. 3 x 305W Solar panels. Power output of the panels were very good until December 2016.. I initially thought all the cloudy days caused the system not to operate optimally. Solar peak use to be just after 12AM and @ 800 - 900W's. It now peaks at about 10AM and only 600W. The ouput Voltage of the panels is still about 119V. Thought that some of the cells might be dead. Measured my batteries individually and voltages seems fine. Angle/ tilt of panels at about 28Deg Direction - Just off North. Question 1: Is it possible that the angle/ tilt of the panels can play such a big role in the effectiveness of the system? Question 2: The inverter comes on for short periods to charge the batteries. Seems that the capacity of the batteries is not what it used to be. I change over to mains power on 47V. New set of Vision batteries installed in April 2016. Might this be because batteries are never really fully charged? I would be glad if someone can maybe give me some advice. Regards

Yes they are still available.

Hi all I have 3 x JC305M-24Ab Renesola 305W panels for sale. Panels to be collected. I live in Centurion. Price: R2 250 each. Would like to sell all three at once. Panels have not been used. Regards Fanie +27826070167

Hi guys. I have the following for sale: 3 x JC305M-24/Ab - 305W Renesola Solar Panels for Sale. R2750 each. Panels are brand new, to be collected. I live in Centurion.

Good day. I have 5 x 100AHr, 12v Royal batteries for sale. Have not used them since April 2016, kept them on C-Tek charger/ conditioner. Price R500/ each. Batteries to be collected. Centurion area.

Good day all I also need some advice regarding the Fan Locked warning on the Axpert 5KVA. All seemed to be working fine till this weekend. I replaced my batteries with new ones and after about half a day the Fan Locked warning [01] appeared and would not go away. At some stage utility charged the batteries and the fan came on and operated as it should, but I still have the [01] warning flashing. Any idea how I might be able to "reset" the warning please? My system at the moment: 1 x 5KVA Axpert, 3 x 305W Renesola solar panels and 4 x 200AHr Vision batteries.
