Common questions

What is the difference between STREAM AC and AC Pro?

The UK specification gives the Pro 1,200W AC output and off-grid use. The AC variant is listed with 800W AC output and without the same off-grid capability. Both are listed at 1.92 kWh; select the exact variant.

Can solar panels plug directly into the AC Pro?

It is an AC-coupled battery rather than a direct-PV model with MPPT inputs. Check the supported microinverter and STREAM arrangement instead of connecting panel leads to an unsuitable port.
