Thanks plonkster, I suppose it should not making a buzzing noise
 

Thanks Chris, that means that you will have to control that geyser to not connect when on battery or when solar can't provide enough power.

Guys (and maybe a girl or two), I need to say thank you to this forum and it's members... You have no idea how much I have learned in the last few weeks about solar that I wouldn't have found anywhere else, and I really appreciate your efforts and willingness to give out your hard earned (sometimes expensive) lessons to others. I don't normally participate in forums, other than a guest or background watcher, but you have made this fun and informative, and are saving a lot of people money. No matter the choice of kit, I have never watched/participated in another forum where this much information and knowledge is shared so freely, and "almost" without "mine is better than yours" attitude (there are a few side remarks, but they are in jest).
I genuinely wish I had joined this forum before my install, there is an amazing amount to learn.
Then the willingness of other members of this forum to give up their time (and a bit of kit), has also astounded me. It is not "normal" chat room/forum behaviour! And for that I thank you again. I am extremely thankful that I joined you, and hope that I can impart the knowledge that I have as well as you all have.
So a general thank you again to all members/participants - I wish i had some of the Admins dosh to dish out to some members (even the quiet ones) who have gone an extra mile to help out someone that they don't know.
Although all have been helpful, I need to mention at least one or 2:
@Energy - This forum is brilliant and your willingness to listen to suggestions to improve is awesome
@Camel - Seriously, this guy went out of his way (completely) to assist in sourcing equipment, and spending his own time, helping a fellow forum member
@jdp, @Coulomb - And many others (just forgot all the nicknames for now) - Software tips/tricks. I couldn't have gotten anywhere without your shared knowledge and input to this forum. PS: With the amount of knowledge that guys like Coulomb have shared (in a forum that isn't even in his home country), I have to wonder if he has a day job! Where do people like that find the time?
In general to all the software guys - Your friendliness and information sharing is awesome, and I hope you keep it up. We all spend many hours banging away at a keyboard to get something simple working, and give up that time by offering that knowledge gained, free of charge, to others. So just wanted to let you know that even the "Lurkers" appreciate it.
Cheers all, have a great weekend... I have a Victron 702, fuses and breaker to install this weekend thanks to @Camel
 

Hi there, my first post on the forum.
My workshop is from home with a few CNC machine's, to run them I need 380v 3 phase power.
My consumption per month is +- 2500kwh,sometimes up to 3500. This is my shop and house together.
I started of by measuring the house only which is +- 21kwh per day (+-630kwh per month)
After investigating inverters to manage the amount of power I use, I realized that I need some special 3 phase setup to manage the 40 amp per phase with spikes of up to 100amps for a
millisecond or so.(ups required)
First of all I calculated the amount of panels needed, not enough roof space for them to start of with, so going off grid not possible and the battery bank and inverters will cost a arm and a leg.
So in November I installed 18 x 250w panels with renesola micro inverters, 6 panels per phase. 9 panels facing east and 9 facing west. This system generated on average 180kwh per month per phase (+- 540 kwh per month total)
This month I added 9 x 310w panels + 5kva mecer inverter and 8 x 200ah battery bank which I wired into the red phase of the house only.
On this phase is all the lights, some plugs and the fridge's. Geysers (solar already), stove, washing machine ens is still on the other 2 phases.
The last 2 days with a lot of washing and tumble drying my consumption dropped already to 8 Kw per day. I will see what the rest of the week happens.
I wonder now if there is something available that I can connect the micro inverters to that can manage the amount of power needed per phase and move one phase that need little to the one that needs more. What happened to day was that the red and yellow phase needed no power from the grid but the blue phase needed a lot, I know the red phase(battery backed up) will be available to help the blue but how can I shift the set of inverters from the red phase to supply extra to the blue phase?
 
Thanks
