Thanks for reply. I agree and appreciate the VERY sound argument.M Sent from my SM-P605 using Tapatalk

Big win... well done.!!! I am as far as moving my geyser to the roof next to the low pressure solar and using a 12V ITS reticulation pump circulating the water. Its wired to the DB on Eksdom but set to 55deg. Solar heats the water and AC keeps it above the 55deg threshold. Plan to go with your solution when I have a lot more panels.

Question for Coulomb Given your experience with the firmware - is there a chance you can change the firmware to increase the upper limit of Menu item 26 (Bulk/CV) so we can Equalise our batteries at a higher voltage (currently 58.4). I was thinking of 62V (or more) as Trojans for example need it to be 61.92 from my calculations and the data sheet. Will the charging circuit allow this... It would make a huge difference to alot of us. Thanks Mark

Looks good... great idea. Looking a bit dry at the back there... hope you got some rain yesterday and last night... We had a surprise 47mm in 3hrs early AM @aloeridge . Very happy!! Cheers M

Of software (edmundp and jdp) both have working versions either available or soon to be available. Need a BMV 702 or 700 as well... Regards M

A simple but not elegant solution is to plug the grid into a timeswitch. I have done that and works well. But dangerous if you dont get sun ie batteries drop to below threshold

Thanks Mike This helps alot, Regards Mark

The way to go for you no question...

Tell us more about the inveter and its settings... dangerous stuff...

PVoutput it Mr TTT

Thanks Mike Do you know if the inverter average the results from the 4 sensors or just take the highest? Regards Mark

Some observations and thoughts on the temp drop. 1. Fluctuates far more than before the fan flip. Could be at least 2 reasons - Fans can now clear hot air in the unit more quickly and so things cool better (and stay cooler). - The temp sensor (would love to know where it is in the unit ) now sees the hot air clearing faster rather than an oven effect. Fans also don't therefore stay on for very long and hence the spikes in the graph. 2. My current temp is 40deg which is 11 deg lower than my previous min at this time of the evening. And its a hot humid evening here. My inside temp is still over 27 deg with 66% humidity. Regards M

The weather and inverter temps can't be muddled anyway. Weather from WUnderground and Inverter from SolarMon. M

So i have a weather station temp and also an Inverter temp displayed on PVO.

Ahhh... Edmund has added some Extended values to the PVO feed to upload various bits from the Inverter and the BMV. Works great. Have a look. For the record. Edmunds SolarMon works very well. The beta version i have is really adding alot of value. Especially wrt Midpoint measurement etc.

Ja Ja.... julle boere....[emoji12]

After seeing another day of 30deg heat here and having had some 37deg days in the last few weeks I today decide to "flip the fans" on the Axpert 5kva 48V. Blow up and not down now! Have a look at my Extended Data on PVOutput: http://pvoutput.org/intraday.jsp?id=46042&sid=42110for more details but I have immediately seen the following: 9th Jan Max/Min Temps = 67/52 10th = 64/51 11th = 65/53 12th = 67/52 13th = 70/54 (before flip @ around 14:30) 13th = Min 38 @ (Inverter on @ 14:53) Max so far is 53 (Which is almost lower than my previous Min!!) RESULT! The flip was easy... you must take out the Serial Board... Regards Mark

Skip that... its the Efficiency that counts

Bump

Max PV today has so far reached 736W (of Panel Max of 600W (2x300)) 2x ReneSola Virtus II 300W Thats 22.6% better than spec. Temp is around 25 deg with scattered cloud. Nice - but does raise issues around fully populating the inverter (Axpert 5/48V) with 3000W of panels... (could get 3650W)?? Regards Mark

Thanks Chris Good luck with your water/stock issues... I hope rain comes soon... Praying for a wet 2016 for the country!! Cheers Mark

No local supplier but Chris knows... I would buy them tommorrow if price was lower and local. H02 covers 4x 12V with one unit but at a much higher price. Thanks Chris for the update!! M

Dankie Meneer... will be good to see SA represented ... lots of Auzy teams...

"Fault code 08/09/53/57 Internal components failed. Return to repair center." This is for the 5kv from the manual... Doesn't sound good. I would first disconnect from power (AC and DC)... and then reconnect... Cheers Mark

Hi All I am finally at 30 outputs on PVOutput . I have created a "Southern Africa" team, feel free to join it if you use PVOutput. http://pvoutput.org/listteam.jsp?tid=1102 (Join or Leave Team under graph) Regards Mark
