hybrid system with wind, PV and storage!

[Alabrese Piero]

Hello to all
I would like to build a photovoltaic and wind system with storage for my home!
can anyone recommend me an inverter capable of managing everything? entrance for:
- wind power-MAGNUM5- Tesup (https://www.tesup.it/product-page/turbina-eolica-magnum-5-12V-24V-48V-italy),
- input for PV (6 or 8 KW plant),
- input / output for the battery pack (lithium or other ??)?

otherwise if there is no inverter capable of satisfying my needs, what can I do?

I read on the forum that it is possible to do:
- PV system with suitably sized inverter (I would like to make a 6-8kw one)
- battery pack for accumulation

the same battery pack will be recharged by the MAGNUM5 turbine that I would like to purchase (obviously with the appropriate charge controller https://www.tesup.it/product-page/regolazione-di-carica-del-vento-12v-24v-48v-Italia )

RIGHT?? is it possible to do it this way?

which batteries do you recommend? there are those who say that lithium ones are not good for wind power ... why? center the charge controller? what do you tell me to do?

if you made a system in this way, what happens when it is night (the PV does not produce) the batteries are charged and the MAGNUM5 produces? is wind power stopped automatically? by whom and how? is the charge controller doing this job? or do I need to add some components?

and then I would have many other questions to ask those who have experience .... but let's do it a little at a time ...

thank you all!

Hi Alabrese,

I don't know of any inverter that allows for hooking up a wind turbine directly. Then again, nearly all off-grid (battery charging) wind turbines come with their own charge controller that is meant to be connected to a battery bank.

When it comes to all-in-one inverters, have a look at the Phocos AnyGrid line: https://www.phocos.com/product/psw-h-hybrid-inverter-charger/
Those are code-legal in Italy, and take care of most of the hardware needed to connect batteries, solar panels, and of course the inverter itself. The wind turbine would connect to your battery bank (via its own charge controller).

There is nothing inherently better or worse to lithium-ion batteries when it comes to connecting wind turbine. Lead-acid or lithium-ion can both work fine for that. Have a look at an article about lithium-ion batteries I wrote (https://www.solacity.com/how-to-keep-lifepo4-lithium-ion-batteries-happy/), it has more general info and should give you a good idea about their advantages/disadvantages. One of the things to watch for is if your wind turbine absolutely NEEDS to see a battery bank, and what would happen if that battery bank "goes away". Many wind turbines self-destruct if they are not connected to a battery bank, and lithium-ion batteries generally have a BMS (Battery Management System) that will disconnect the batteries if the BMS senses that things go outside safe parameters for those batteries.
