Off-grid system

[rafaelt]

Hello,

I am thinking installing a photovoltaic system in my house in Spain. Unfortunately the spanish legislation penalizes self-consumption so my idea is to install an off-grid system.

With an estimated consumption of 8 kWh/day obtaining the following system:

My doubs are these:

I get two types of battery (OPzS and OPzV). Can I do OPZS maintenance or do I need a professional? Worth the difference in price?


If the law changes and I want connect my system to grid, can I make this by changing inverter and remove the batteries or I need other changes in my system?

Thanks.
