Vorajeeeee

As far as I know, the Fronius Primo is a PV inverter & not a battery inverter. In other words it's Grid tied. It cannot make use of a battery. The Sunsynk is a Hybrid, The primo in this particular case cannot use a battery. Maybe there is a model that you are aware of that is more advanced that can accept a battery? 

I'm totally for this! Now just to find out how to enter

Hi Guys so here is another GIVE AWAY!
We are busy with a test and review of the Greenrich 1.5C 3.686 kWh Lithium Battery 
Yes we will be giving one away to one lucky Power Forum Member in a Lucky Draw 
I will post details on how to qualify for this GIVE AWAY soon watch this space!

So some information to wet your appetite about these batteries 
Greenrich batteries have been in the market for some time now and so far we have had mostly positive feedback from installer and end users alike.
What makes the battery desirable is the 1.5C Rating this means the battery can discharge at 1.5 times its capacity rating.
Why would that be so great?
Here is why if you have a 5KW inverter discharge the battery at 5kWh then this 3.686 kWh battery will be able to absorb a charge rate between 0.5C & 0.75C and a discharge rate at 1.5C without tripping the benefits of that is that when you start of on your solar journey you don't have to break the bank with just one 3.686kWh Greenrich Battery because your 5KW inverter can never reach the discharge rates of the battery. 
The 3.686 kWh is also inter compatible with the 4.95 kWh Greenrich Lithium if you require to expand to larger capacity.
This Lithium battery is the only Lithium battery in the market that offers true 1.5C discharge ratings. With 1.5C discharge rates, the Greenrich lithium battery has a much higher power output compared to other 0.5C or 1C lithium batteries. 
The cell technology in the battery is LFP cylindrical high density cells which can do up to 2C however for longevity the BMS limits the discharge  to 1.5C and charger rates to 0.5C continuous and boost charge rate for 5 minutes to 0.75C
