Hi August,

We're starting to install the Tesla Solar Inverter with good results:
https://www.tesla.com/support/energy/solar-inverter/tesla-solar-inverter
It is going to be a tough product for others to compete with - the
price point is low and features are high. 4 x MPPTs with low tracking
voltage (60 VDC), built in consumption monitoring, one SKU to handle
7.6 kW, 5.7 kW, 5 kW, 3.8 kW AC rating via software programming, built
in ethernet/WiFi/cellular and the rapid shutdown can meet the NEC
hazard control system requirements meaning that only one Mid-Circuit
Interrupter (MCI) is needed for every three modules. All in all, a
solid offering with lots of design flexibility. Time will tell how
reliable they are.
Best, August

We generally avoided using the 41 series inverter for reasons
specified here [1]. If you find a new string inverter in the SMA
lineup, you might want to check to see if they have resolved some of
the shortcomings.
I have not had reason to use string inverters because, other than
Solar Edge, they do not offer intrinsic rapid shutdown. Careful
reading of the NEC indicates that even ground mount arrays require RSS
unless the PV feeders run to a building with the sole use being to
house solar equipment. Having said that, I would imagine that if an
inverter were mounted on the ground-mount rack, the requirement for
RSS could be avoided.

What are you wrenches that used to install the SBXXXX-41 units
sourcing now? Looks like there is a new model on their website
