                                              <div>The current trend of
                                                manufacturers
                                                resisting issuing RMAs
                                                is concerning. The
                                                amount of work they want
                                                us to do to confirm
                                                their problem is
                                                staggering (Looking at
                                                you SolarEdge). With
                                                that said, we only have
                                                7 systems with HomeGrid
                                                batteries. We have had
                                                only one issue with them
                                                and it was firmware
                                                related. Unfortunately
                                                their firmware upgrade
                                                process is a total
                                                kludge so much so that
                                                like Jason, I  just let
                                                them take over my laptop
                                                and let them handle it.
                                                It really made me
                                                appreciate Discover's
                                                software and firmware
                                                update process. We have
                                                a lot of Discover
                                                batteries out there and
                                                like the EG4s you can
                                                just shut off the bad
                                                battery and move on. In
                                                addition, if you have a
                                                battery module that is
                                                "dark start low" you can
                                                actually "charge" it
                                                (it's more like spilling
                                                electricity) from a good
                                                battery in the stack by
                                                turning off all the
                                                loads and charging
                                                sources (i.e. the
                                                inverter) and all the
                                                battery modules except
                                                one good one and the bad
                                                one. After you get the
                                                low one to a decent
                                                state of charge you can
                                                fire everything up and
                                                put a good balance
                                                charge on the entire
                                                stack. I have found
                                                their support to be
                                                great as well. They also
                                                just took their remote
                                                battery monitoring out
                                                of beta so now you can
                                                see battery info
                                                directly online. Which
                                                is nice. I am a big fan
                                                of having
                                                redundant monitoring so
                                                we can "trust but
                                                verify" the data being
                                                reported by the various
                                                components. I am still
                                                bummed they ended
                                                production of
                                                the 42-48-6650, the
                                                build quality was
                                                ridiculously good. I am
                                                little leary of
                                                their replacement,
                                                the 48-48-5120, but it
                                                seems to be doing fine
                                                in our installs. It has
                                                only been a year or so,
                                                so the jury is still
