Tigo Retrofit TS4-R–O Optimiser
The TS4-R is a Retrofit or Add-on universal base. The TS4-R addresses the need for a retrofit solution that can be mounted on any existing installed PV system, connected into the existing PV module JBox, improving energy harvesting, greater flexibility, and increased control over project to the existing PV system. The offering for the retrofit is a two-piece solution: the TS4-R base, which is added on the solar module, and its covers, plug-and-play Flex MLPE which can be swapped in and out. It supports any of the wide offering of the existing TS4 Platform functional covers. It can also be designed into a new system.
TIGO Advice For Retrofit Panel Replacement
Tigo can work ‘plug and play’ on any module under 52 Voc, and is compatible with any inverter.
Tigo should ALWAYS be installed on the LOWEST Wp module in a string, NOT the larger Wp modules in a string. Therefore if you used a higher Wp replacement module, all the other existing lower Wp modules would need optimisers, so would not make any sense using a higher Wp replacement module. Therefore ALWAYS use a lower Wp replacement module.
If you are installing Tigo even on one replacement module in a string that is connected to an MPPT tracker which has other parallel strings attached, then every module would need Optimisers to be able to function correctly. Therefore makes sense to ONLY install Tigo on a replacement module if it is on a string on its own MPPT tracker. This means careful re-jigging of the modules to ensure any replacements go on one string on one tracker.
