I can now confirm my victrons cpu version is 2659150.hex, so theyare the new version.

Thanks Jaco, The Systems certainly keeps the lights on and make 38KW/h on a good day, but I have a shading problem on the one string in the winter, which was a design compromise when I designed the house, but watch this space, I am busy cooking up a new plan.

Thanks for interest. I uploaded my my setup on the member showcases page for more info.

External grid : Eskom (old Rotating meter store exess power in grid, to avoid cycling batteries at night) Hybrid inverters: 2 X Victron Multiplu 48Volt/5000VA/70Amp, (master slave parallel operation give 10000VA), Victrons Include multistage chargers limited to 60A+60A=120A Battery charging current. Internal Grid: 2 X Eltek THEIA HE-t 4.4 grid-tie inverters providing power directly to load at 97% effeciency. excess is routed back to grid or batteries by victrons. The Victrons also Throttle excess power on Eltek's through frequency shifting when eskom down. Batteries : 24 X 2V @ 500A Lead Crystal Batteries CNF J-500, providing 48V @ 500A 20 X 305 W Monocrytaline panels , arranges in 2 strings of 10 panels at 360V feeding into the two Eltek inverters respectivly A BMV-600S battery monitor tells, what coming and going. Effergy engage, cloud based power monitor keeps track of usage.

Thanks for reply gents, I have no idea what the cpu version is, sitting in Congo at moment. will have to check when back in three weeks Also I have not contemplated an exact price yet, but was looking at R50k for everything. Remember the one Eltek needs to be repaired. I think this is a good price even just for the two victrons. I really love the victrons and its a pity I can't incorporate them into my new integrated hybrid design. hope they find a good new home ;-)

I am doing a forklift replacement on my system and will have some kit up for grabs: I have two Victron multiplus for sale. currently installed in parallel to give 10KW. Hybrid bidirectional operation, can mange grid-tie inverter power through phase shifting and has a powerfull multistage battery charger. I also have two Eltek THEIA 4.4HE-t Grid-tie inverters for sale, one needs to be repaired though. please let me know if you are interrested the units are almost 3 years old. The Victrons are really excellent units.
