I have a 400w panel on our camper connected to a Victron SmartSolar MPPT 75/10 and a 24v battery bank. The van is sitting parked most of the time and I’m wondering what I would need to do to connect it to the house to supliment the 240v house power? Like these plug and play kits do with a micro inverter:

Does Victron offer any product like this that will fit with my mppt?
Thanks
No micro inverters from Victron available.
And also no, you cant use a micro inverter with an mppt on the same string of panels. It is either or.
You could add a 2-way switch to the PV module cable, so you can switch between EITHER the Victron MPPT connected to the PV module OR a micro inverter connected.
For 400W (before conversion overheads, losses etc, it would take a lifetime to pay off the additional gear. Juice isn't worth the squeeze.
You don't say what else is installed. But cheapest option would be a 24V charger. For example the smart IP43 range

Thanks for the responses. Very useful.
I roughly calculate (based on the performance of my 6.6kwh home pv system did last year) that a 400w panel should produce enough power to save me €130 per year of peak rate grid power (here in Ireland).
The hoymiles HM-400 is what I was looking for, but it gets quite pricey if you add on wifi monitoring. So this VEVOR Solar Grid Tie Micro Inverter 600W model (with it’s own app) looks more suitable:

I guess I can just unplug the panel on the van roof and plug in the vevor to the mc4 connectors there. Just have to remember to disconnect when I need to drive off in the van!
Sounds good. But please check if this Microinverter has all required certificats you need in your country. I don't know what is needed in Ireland, but this product you mentioned, looks like one of these chinese products without any reliable quality.
