January 9, 20251 yr I have a 50kW deye system with a stack of Lumo HV Batteries, If i want to add another stack of batteries, will i need to upgrade my inverter?
January 9, 20251 yr Just to clarify 1) Is it a 50kW or 5kW inverter? 2) What is the capacity of the current battery stack in kWh?
January 9, 20251 yr No need to upgrade your inverter. Energy storage is not dependent on the Inverter to handle that storage. Eg. You can have a 5kW Inverter that has 100kWh of battery storage, the only question comes when designing such a system is how will you charge such a huge battery bank. In your case depends how many panels are attached to make it renewable from the Sun or will you accept Grid Charging as an option??? So simple answer no. Don't need to upgrade your inverter. But that depends on your charging & load requirements to fill up this larger battery.

So each Lumo HV battery has a capacity of 5.12kWh so the full stack has about 51.2Kwh (its a rack of 10) and I am currently using a Deye 50kW 3 Phase Hybrid system. I was curious if i needed to upgrade because of the charge and discharge current, incase it would go over the capabilities of the Deye 50kW. I am currently running 108 panels.
January 12, 20251 yr Energy storage is just potential energy. You won't exceed anything on the inverter. It's like hooking up batteries in parallel to your motor car, you car would still just use what it needs from the battery. The inverter is the same, you are adding potential energy that can be used by the inverter whenever it needs it. Maybe another simple explanation is fuel inside your cars fuel tank. You can add an extra external fuel tank & that means you car can travel further but it won't damage the engine in any way.
