Choosing the right Inductor for aftermarket inverter motherboard

Fabian

I am rebuilding my 48v 10,000 power jack split phase inverter that uses a EI type transformer by installing a aftermarket pure sinewave inverter motherboard.

The problem i am facing is that i am not sure which size amp and UH inductor to use because this is a requirement for installing the new board. 

The inductor will decrease the standby current of the  motherboard but u have to choose it correctly for it to work good.

Please take a look on the motherboard and also the size inductors in the links below and tell me which size inductor i should use.

One possible idea--If you have longer periods of low/standby power usage (LED Lighting, Security System, etc.)--Install a second smaller AC inverter to power just those loads --was save running the larger inverter for those "large/optional" AC loads.

In the 'olden days', there were not many "low power" 48 VDC inverters out there... Today there are quite a few options.

I already know about that. I just want to rebuild the inverter asap but want to purchase the inductor but confused as to what size to pick. Please help me guys. I

Without the specific technical specifications (datasheet) for your new inverter motherboard, anyone who suggests a specific inductor value (µH) and current rating (A) is making a blind guess. Using the wrong inductor can lead to immediate failure (burning out the MOSFETs on the board) or poor performance (low efficiency, overheating).
