When I had my system installed they didn't have the Lynx shunt available. So they used a 500a Smart Shunt. I have since replaced with the Lynx shunt. What can I use the extra shut for? My system is in a 5Th wheel camper I have 1200 watts of PV, 2 Battle Born Game changer batterys, 150-100 MPPT, Multi plus II 3000 12v, Lynx distributor and 1000a Shunt, Cerbo GX and the display, I want to put the extra shut to use if possible, if it's not practical to use it I'll just save it in the rare case the Lynx shunt dies.
