4watts Is this the DC breaker between the batteries and the inverter or the AC breaker between the inverter and the distribution board?
If it's the DC breaker then it is possible that the terminal screws need tightening. If slightly loose they warm up causing the breaker to trip prematurely. I have had this twice now in 2.5 years of use and each time I could tighten the screws a bit. Be careful to make sure it is all de-energised if you want to do this yourself or ask your installer to come back (or any electrician should be able to help).
In the meantime change the charge and discharge powers from/to the batteries to see if it helps.
Originally I thought this was a poor installation where cables were not terminated correctly but I understand that GE have changed the method and now include the DC breaker in the cabinet and use a different connection method. Apparently DC breakers tripping is a common problem.
PS There's a thread on the GE forum with more advice (but you have to wade through a lot of mis-information).
