Efficiency of getting second 3.6kwh vs upgrade to 8.8kwh?
I've decided 16A isn't enough. Seems like my options are
Replace my 3.6kwh ECCO with an 8.8kwh, maybe ebay the old one.
Get a second 3.6kwh ECCO and parrallel them.
Both options would suit my requirements, parrallel would be cheaper up front but I could imagine running two inverters consumes more power and could tip the balance over a number of years.
Has anyone looked at power overhead for different configurations?

If you already have a 3.6kwh then add another one.In that case if one should break you still have the other one to work with.If you replace with 8.8kwh and it gives truoble you have nothing to work with.
