What is Inside My Inverter?
Hello Everyone
This thread is Made To Help you know the Inverter internals, Considering It A Good Judgment of its quality, Spec, and true capability in comparison between them.
In this thread, you will find pictures that contain inverters Model, MPPT Specs (Some of it), and weight
this information is gathered from Inverters Datasheets and Main Boards Sellers (MPP Solar Distributor) and Repair Videos and will add more Model when good intel found or Provided.
- From the included Picture (Considering it the True Voltronic design not a cheap Clone) :
1- it is noted that the VM III 4kw, 6kw Similar to the Original VM III with an extra Aluminum Cooler on the MPPT and One Less Bus Cap
2- VM II 5.6kw Almost Equal to VM III 6kw (Without The Extra Aluminum Cooler on the MPPT) But use different UI (VM II's) and Less Software Features
3- King II 5kw is similar to MKS IV 5.6kw but the MKS is A higher end Model (Extra Components)
4- VM II 5k Premium Close to VM III 6kw Twin but Have a separate MPPT Board (Preferd Among Technicians) and Extra Bus Cap
5- Felicity Solar Inverters Uses Different Design Than Voltronic (And Have Way Less Models) Closer In Design to Mks Models Components Wise (Separate SPS Board + Not Negative Liner Voltage Regulator + RTC battery on the Main Cpu Board Like Mks)
The Thread contains these 24v and 48v Models:
Felicity Solar: IVEM 3024 - IVEM 5048
Voltronic: King II 5kw - MKS IV 5.6kw - VM II 3k Premium - VM II 5k Premium - VM II Twin 5.6kw - VM III 4kw Twin - VM III 6kw Twin - VM III 5kW

Note: Voltronic Mix and Match and rerelease same model name with different/extra features Example (VM II: they added Twin, Premium, Premium Lite, Elite, Premium Plus).
Note: There is alot of Cheaply made inverter with same looks and models with cut down components and cheap semi conductors this Thread dose not factor those Models in the comparison and not responsible for any Misguiding from cheap clones.

Expert Feedback is Welcomed

Adding More Models (2025-5-16):
MPS-V 3500w Plus this model is a modded Voltronic clone (Probably from Sumry Factories) with separate MPPT, and have 12 Mosfet on the input section with VMII interface (Better than the Voltronic VMIII 4kw Models Component wise (more Bus Caps and Input Mosfets and one more transformer).

King II Have 3 inductors 2 on the main board and one on the MPPT from looking at these pictures ( could 0 ms transfer be achieved with the extra coil to get 0 ms transfer time?)
MKS have a 2 inductors one on the main board and big one for the MPPT screwed to the chassis and the main board have more varistor and Mov's and thicker coolers for sps semi conductors
Edited to correct a technical mistake between online inverter and 0 ms transfer time
