Members are seeking clarity on which converter/charger and inverter models are installed in the 2023 Micro Minnie 2108FBS and 2108FLX, especially when upgrading to lithium batteries and considering inverter prep. The consensus is that the 2108FBS typically uses a WF8900 series converter with auto changeover for lithium, likely the 8955-AD (55 amp), while the FLX models are reported to use Xantrex 2000W or 3000W inverter/chargers. For the 2024 models, inverter prep wiring is standard, but for...

Members are seeking clarity on which converter/charger and inverter models are installed in the 2023 Micro Minnie 2108FBS and 2108FLX, especially when upgrading to lithium batteries and considering inverter prep. The consensus is that the 2108FBS typically uses a WF8900 series converter with auto changeover for lithium, likely the 8955-AD (55 amp), while the FLX models are reported to use Xantrex 2000W or 3000W inverter/chargers. For the 2024 models, inverter prep wiring is standard, but for earlier models, heavier gauge wiring is recommended if planning to run high-draw appliances like microwaves or air conditioning.
Members advise that running both the converter and inverter simultaneously can create a charging loop, so it’s best to turn off the converter breaker when using the inverter. Some recommend keeping the converter for charging and adding an inverter separately, as switching to an inverter/charger is a more complex and costly modification. There’s also discussion about battery placement and wiring logistics, with suggestions to consult Winnebago for schematics and to consider independent technicians for advanced installs. Real-world setups range from basic lithium upgrades to extensive battery and inverter systems, with most agreeing that running air conditioning off-grid requires significant battery capacity and a large inverter.
