Introduction
In order to increase the feasibility of solar as a widely used source of electricity, the cost simply must come down. In recent years the cost of PV modules has dropped significan...

Modules that are older or have lower voltage or current ratings can sometimes be connected to a single optimizer input as long as they do not exceed the ratings of the optimizer. For example, two l...

Yes, as long as the module specs are compatible with the optimizer. See the Design Tool for more info. You can use the set screw on the optimizer to mount it on the racking.

Bypass diodes allow current to flow around shaded cells to reduce power loss and avoid creating hot spots in the module (since power loss is dissipated by the cells as heat.)

All Tigo Optimizers are dual rated: 600V/1000V. Most cables say “600V UL” and then “TUV 2 PfG 1169”, which is the TUV 1000V certification. The 1000V UL cables say “1000V UL” and have Amphenol H4 or...

Optimizers will continue operating until the smart module reaches the minimum voltage, about 10V. Optimization and monitoring will resume when the optimizer is back in normal operating voltage range.

Optimizers use an electronic switch instead of a relay. This electronic switch is rated to a voltage that is more than twice the optimizer voltage at maximum power, so it is typically working at lo...
