Request for Firmware Update File - OPTI-Solar SP4000 HANDY PLUS

Hello everyone,

I currently own an OPTI-Solar SP4000 HANDY PLUS power inverter. I would like to get the latest driver update for my device.

Here are the current driver versions:

• Main processor driver version: 00057.00

• Secondary processor driver version: 00119.14

Can anyone tell me where to get the official driver update, or share the file if it's available?

I tried contacting OPTI-Solar directly, but I wanted to ask here as well, hoping someone here might have experience with this model and be able to help me.

Thank you so much for any help you can provide!

Thank you in advance.
