Hi Pap.

The mppt and the solar is a good match.

But that's a massive inverter comparatively, and an anaemic batt bank will likely cause issues on both charge and discharge sides.

Victron's take on it is summarized here: https://www.victronenergy.com/live/battery_compatibility:pylontech_phantom Allow for the batt sizes discussed there.

They don't/can't speak for Pylon, but imagine a warranty claim on the batts, and you tell them a 10 kVA Quattro. connected.

You're right to have concerns. You should also speak to Pylon, and even see recommendations in writing to feel safe.

Whether grid connected or no may make a difference too, and how it's all set up. But the batts do seem too small..

Hi John. Thanks for the reply. I did read that article and that was why I posted this question.

Some more information. I am in South Africa. JHB. The set up will be grid-tie. I was looking at the following usage set up: Solar, Battery and Grid. Solar as first priority, when solar is not available battery to 60% and then switch to grid

Your thoughts?

Also depends on where in the world you are and how your household is set up with regards to energy consumption. Are you running a solar geyser? LED lights? Cooking on gas? As for me i am in Cape Town and running all those things and i have no problems filling 2x 4kWh BlueNova in summer with 13x 270W panels and a 5kVA Multi II. You probably need to provide more detail for people to be able to give you a more elaborate answer.
