About Photovoltaic Energy StorageDo not use capacitors in circuits intended for rapid charge and discharge cycle operations. If capacitors are used in the circuits that repeat a charge and discharge with a large voltage drop or a rapid charge and dis-charge at a short interval cycle, capacitance will decrease and/ or the capacitors will be damaged by internal heat generation.
About Photovoltaic Energy StorageUsing the right size capacitor is always recommended. So, when it comes to using a 5 capacitor, it is much smaller than a 7.5. So, even if you replace the capacitor, it is unlikely that you will receive a satisfying or close to the expected performance. Can I Use A 10 Capacitor In Place Of A 5? The rule is slightly different here.
