[QUOTE="michael8554, post: 531337, member: 34375"] My house has two 100A main fuses. Effectively one to feed the storage heaters. And one to feed the CU. Via an Off-Peak contactor system. 1. So for the Storage Battery Inverter to accurately measure the grid feed in/out, I believe I will need two Current Transformers, one on each of the 100A feeds ? 2. Can I locate the CTs close together and wire them in parallel to one long cable to the single Inverter CT input ? Or should they be connected to the one Inverter CT input by individual cables all the way ? 3. Researching this, I have also seen suggestions that the CT's should be wired in antiphase to each other, does this make sense ? Thanks for looking. [/QUOTE]
