Hi,
I've got a SmartSolar 150/35 with a string of panels totalling 600W. I've a couple of 110AH TN Power LiFePO4 batteries in series so running at 24V.
I've also a Phoenix Inverter Smart 24/3000. Both the charger and inverter are connected in parallel to the batteries via fuses etc. Cables to the inverter are 50mm2 copper and 16mm2 to the charger.
Generally on its usual load (around 150W) everything is fine. The 'fun' starts when I charge the car....
I've set that rate to 1.3KW which the inverter is fine with and it charges nicely. One of the batteries gets a bit warmer than the other but nothing to worry about. But the yield from solar drops right down from say 400W to under 200W. I note that the panel voltage also drops from around 95V to 50V as well. It's almost like the MPPT tracking has gone wrong somehow. Stop charging in the and it all recovers.
Ripple up the DC to the charger upsetting it? Something else obvious I've missed?
Cheers
Phil
