Hi
I had my Fronius Symo 20 kw grid tied inverter (3 phase) installed with 8kw Trina 305 watt solar panels a week ago
1. phase 2 is that I now want to install batteries for night time use but also as a backup if our electricity provder sheds loads - up to +- 24 hours
2. I bought 24 batteries (2.2 volt and 875 amp hr each) which I want to connect to give me 48 volts and 1750 amp hours (bought these batteries at a very very special price from a reputable supplier)
3. my question is what more will I require (e.g inverter, charger etc) to connect the batteries to the Symo inverter (remember it is a 3 phase system)
4 i want to keep the Fronius inverter - costed me an arm and a leg for the whole installation and cannot afford a whole change over now
5. I would just like some short explanation on how to do it and what to buy
Kind regards
Frans
