For domestic I used 8kW victron Multiplus II with a 250/85 charge controller and 8x555 Wp panels and 3 eTower batteries.
For the Pivot I used 36 x 555 Wp panels in 2x 18 strings on EM Heater solar VSD’s. 1 11 kW vsd for a 9.2kW borehole pump and a second vsd 15kW (over sized to handle dol wheel supply) for the pivot drive.
1 string of 18 of the pivot panels has dual function with a change over to a 5 kW Fronius on the Multiplus (ac coupled). When pivot is not running, the fronius soaks up early and late solar.

Off grid 3 phase system. 3 x 8 kW Multiplus II, with a 3 ph 6 kW Fronius on AC couple, 3 victron charge controllers. Total 36 x 545 Wp ja solar panels. Old lister 3 phase gen on multi ac input. 4 x eTower 5000 batteries.
If anyone has done an AVR on old generator it would help this old Kit. Hoffberg alternator, 7 kVA. Excitation 12 V 5 Amp.

Phase 3 now completed. I have moved all DC into a db of its own. DB for AC change over and fronius input. Add a 250/70 smartSolar charge controller with 8 x 370 Wp artsolar panels. Added a smart switch to prevent the fronius tripping the system when the grid fails.
phase 4 will be to add 2 more batteries that i bought in July 2019 and still waiting for a certain Mr Jacco Jackson to deliver.
now i have:
15x310 Wp in series on a fronius 4 kW grid tie connected via an acdc smart switch to AC1 out of a multiplus 5kW.
8x370Wp on a smartsolar 250/70 (2banks of 4)
2x EMS 48100A1 li-ion batteries.
Eskom must do what they like...

I started research into solar 2 years ago. Choose to go with a Fronius Primo 4.1. Great that it has 2 mppt and 1000 V DC. Commissioned 1 Jan 2018. Have 15 renewsys 315 Wp on MPPT1.
just added a Victron Multi, ccgx and li-ion batteries to the system so that i can more fully utilize excess solar.
