About Photovoltaic Energy StorageI thought C4 would only accumulates positive current from IC7''s pin 3 and release it to IC6''s pin 4. I thought the capacitor should be hold fixed to connect one pin to positive, and another to negative. From what i can see the IC7''s pin 3 is switching from positive current and then to ground on one of the pin of C4. Thank you
