Hi
First time here.
I am in the process of deciding on a battery storage system to add to my existing AC coupled PV system, 4kw, east west split system so max geraration as anyone time is 2.5kw. UK with feed in tarrif meter
Thinking of getting the Multiplus II inverter, however, i am a little confused on what other modules I need to take into account for costing purposed, other than batteries. There seems to be shunts, battery monitors etc. Planing on using the system to maximise the amount of generated solar as I currently export a lot to the grid during the day whilst a work and then importing from grid at night
Other than the inverter, what other compnents would i need to control the system and to automatically monitor current excess solar and use it to charge batteries and then draw off the stored power when solar is low / unavailable. Also interested in monitoring system via smartphone app
Grid is very stable in my area of the UK so not thinking of configuring the system as emergency backup in event of power cut, purely storage / use of excess generate solar
Thanks in advance
