Use victron charge controller with MPP inverter

Hi All,

I have smaller solar setup that I'm planning to bigger one. I recently purchase one Pylontech US3000C rack mount battery for this upgrade

New items

I tried to purchase victron mutliplus inverters and there's no way I can get it from my location. Also I was trying to get inverter from Meanwell, but lead times are very long. So I'm thinking to go with MPP solar units. I have few questions regarding this.


1. MPP units has MPPT charger inbuilt. but still I like to use my trusty victron MPPT charge controller for charge pylontech battery. is this possible ?

2. If I connect MPP inverter battery IN to the pylontech battery which also connects the victron charger, does it damage my victron charger ?

3. what are the items need to communicate with Pylontech battery from victron mppt smart charger ?

4. if above configuration can be done, can I connect the MPP 3kv inverter to my small charge controller load output ?

Also I really like to use all victron products. since no way to get it for my location. I was thinking to go with cheaper chines brand first and later upgrade to Victron if possible

Any input on this really appreciated

Thanks

You have the wrong MPPT and panel combo.

2 panels in series (required for charging a 48v battery) will go go over the mppt's max input PV voltage of 100v.

JA solar 460w panel.

Victron online MPPT calculator.

Hi, thanks for the reply. this calculation based on around -25F low temperature right ? The location minimum temperature will not go down more than 68F. and we only getting 46voc max from the panels. so adding 2x those in series and 2x strings in parallel wont exceed the 100/20 controller ratings. that's what I got from this calculator.

So based on the values I thought this controller can handle the 4x panels. correct me if I'm wrong
