FAQ Legacy Tigo Equipment

  • [Legacy] Cloud Connect: Configure Wi-Fi Internet access
  • Internet access is required for Cloud Connect to upload data collected from the Tigo TS4s to the Cloud servers. This is how your account's System View receives its updates. Network changes (like re... See more
  • Application: BOS Savings
  •     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
  • Are the Legacy Smart Module J-boxes removable?
  • 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
  • Are TS4 backward compatible with legacy system equipment?
  • 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
  • Can I connect more than one module to a single optimizer input?
  • 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
  • Can I use optimizers with frameless or bi-facial modules?
  • 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
  • Cloud Connect and Maximizer Management Unit Control Panel Menu Reference
  • This article provides the menu options for the Cloud Connect and Maximizer Management Unit:   Cloud Connect (CC) Maximizer Management Unit (MMU)   General MENU operation: Press MENU button, then... See more
  • Cloud Connect Overview (Legacy)
  • 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
  • Do Smart Modules and Add-On Optimizers offer the Same Functionality?
  • Add-On Optimizers (ES and 2ES series) and Smart Modules (JES series) Feature Add-on (2ES, ES) Smart Module (JES series) Optimization ✔ ✔ Safety ✔ ✔ Module-... See more
  • How are Tigo Optimizers Different from Microinverters?
  • 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
  • How are Tigo Optimizers Different From Other DC-DC Optimizers?
  • 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
  • How do I use a dual optimizer (2ES) on a single module?
  • 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
  • How is the Optimizer Protected in Case of Ground Fault (Positive or Negative to Ground)?
  • 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
  • How long are the leads on Tigo optimizers?
  • 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
  • Maximizer Management Unit (MMU) Overview and Troubleshooting (Legacy)
  • The MMU (Maximizer Management Unit) is Tigo's first model of System Management devices (or Data Loggers). This article covers the MMU's physical components and the most commonly used troubleshootin... See more
  • What Happens If an Optimizer Fails?
  • 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
  • What is The Device Rating for the 2ES Optimizers, Smart Modules, and TS4?
  • 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... See more
  • What is the Jbox rating?
  • Electrical Ratings MM-JES50 / MM-HBF50 Nominal Input Power 375W Absolute Maximum Input Voltage (Voc): 52Vdc MPPT Operating Range 16-48Vdc ... See more
  • What is the Maximum Temperature of 2ES50 at the Rated Current?
  • Maximum internal temperature for MM-2ES50 is 110C-120C. In standard operation conditions, meaning installed in a system with up to 25% mismatch, Tigo Optimizer dissipates about ~30C. That means tha... See more
  • What is the minimum voltage required for an optimizer to function?
  • 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. See more
  • What is the Net Heating Value (Calorific Value) of 2ES50 at the Rated Current?
  • At rated current, in steady state condition: 0.96Cal/sec See more
  • Which module manufacturers have a Tigo integrated solution?
  • Integrated PV-Modules are a legacy product, and no longer produced. In the past, Tigo had formed limited product partnerships for MLPEs that were married to another manufacturer's PV-Module. Tigo n... See more
  • Which type of switch do the optimizers have?
  • 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... See more
