August 15, 20224 yr So August started with a bang. The cold weather the last 2 days brought very good yields along. Nearly as good as the best summer days. Lines are at 2.5 5 7.5 10kwh on a minute 1.62kw system. Edited August 16, 20224 yr by Scorp007

August 16, 20224 yr Adding mine as well - been pretty decent and also managed to really bring down that Eskom usage
August 16, 20224 yr Can you please specify the amount panels and wattage when you post those figures. Edited August 16, 20224 yr by PowerUser
August 16, 20224 yr My figures generally mirror what other folks are posting, except I had low PV on August 2nd as well as on the 3rd. So these things can be very local. Since the 4th there has been much PV happiness for my system.

August 16, 20224 yr Here is mine I see we all had a bad day on the third of August. 2 growatt 5000 ES --- 12 X 410 Kw panels ---2 strings of 6 each Not worried about cycle count LBSA batteries BMS has a stupid way of counting cycles. Edited August 16, 20224 yr by Antonio de Sa
August 16, 20224 yr 16x400W PV in 2x8 strings EDIT: Updated for full month of Aug 2022 NOTE: Can only generate PV as much as I can use as I don't currently grid feed. Most afternoons there is some clipping. Looking at mining to make use of the afternoon excess. Edited September 1, 20223 yr by system32

August 17, 20224 yr Pi$$ poor performance from my 12° roof since about April. 6.37kWp system battling to get to 16kWh per day. Looking at tilting up the second row of panels. Analysis of NREL data shows I'll get a 17% improvement in the May - Aug trimester on that half of my panels if I tilt it to 30°. Now the question - which is the better spend? Do this or just add a few more panels, properly angled of possible?

What is your roof angle? Care to share daily graphs for the 3rd and 5th? Edited August 17, 20224 yr by Scubadude

Care to share daily graphs for the 3rd and 5th? My roof is the standard angle, I think around 20 to 25 degrees but does face exactly north and not much shading... 3rd: 5th: Edited August 17, 20224 yr by MakoShark
August 17, 20224 yr Mine is perfectly north but only 12° slope and a palm tree either side causing morning and afternoon shading in winter. My sad picture for the 5th ...

Nice dashboard - I've updated one of my boring tables to include "Cell display mode" Q1. How to you record Average Cloud Cover - do you have a weather station or something? Q2. Where to do get the load shedding schedule? Thanks in advance.

Thanks in advance. @system32 First let me tell you I am BC ( before computers ) All the info I get from my inverters and battery was programed and constructed by my son, he is a "boffin" in software programing ( I like to brag about it ) he got the Modbus protocol for the growatt and for Seplos, the BMS that LBSA uses in theyre battery. The info for the load shedding is pulled out from Eskom site and the cloud cover from some weather site. Herewith some of the info we get from the battery BMS.
