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... See more

Tigo's Legacy Smart Modules are no longer manufactured or sold, but they came in 3 varieties: Trina Smart Module Smart Module J-Box TS4 Cover for Smart Module Each version of the Inte... See more

The short answer is: Yes, Tigo's TS4 family is backward compatible with earlier MLPEs and legacy system equipment. However, some older products may not have the function that is desired from the ne... See more

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... See more

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. See more

The Cloud Connect (CC) is Tigo's second generation of System Management devices (or Data Loggers). This product is no longer in production and may no longer be eligible for RMA replacement under Ti... See more

Tigo Energy optimizers do not convert DC to AC. Our DC-DC solution enables greater energy harvest because it is 99.6% efficient and the installation benefits from highly efficient central inverters... See more

Tigo optimizers (for Smart Modules and retrofit) are compatible with any inverter technology that exists at the market at the time of manufacturing. This enables system designers to keep working wi... See more

If your system has an odd number of modules per string, you can use a dual optimizer (2ES) on a single module by connecting the pair of leads marked Input A to the module, and connecting the pair o... See more

The optimizers - Smart Module Jbox or retrofit add ons - are not grounded. In case of a ground fault to P or N (meaning an unintentional short between ground to Positive and / or Negative) the op... See more

The leads for the typical Smart Module Jbox are 1.1 meters. The leads for the 2ES (retrofit) are 1.3 meters standard. Tigo offers an XL version of the 2ES retrofit that has 2.1 meter leads. See more

Yes, the Cloud Connect is the newer of the 2 Data Loggers. However, both the Cloud Connect and MMU are no longer manufactured or sold, and are considered Legacy equipment. See our Downloads Center ... See more

The MMU (Maximizer Management Unit) is Tigo's first model of System Management devices (or Data Loggers). This product is no longer in production and may no longer be eligible for RMA replacement u... See more

If the system is an early adopter of Tigo products, it may have an older Data Logger, as shown here: Maximizer Management Unit (MMU) Cloud Connect (CC): These legacy units are still empl... See more

Tigo optimizers are factory-configured in the "on" position, which means voltage as high as open circuit voltage (Voc) is present at the outputs as long as a PV module is connected*. In most cases,... See more

The MM-2ES shuts down, sends 'output over current' status and all other standard readings as usual, such as current and voltage. The optimizer waits in OFF position until the Management Unit (MMU) ... See more
