Pros
- Replaces the whole WF-8900-AD panel with the same cutout, so breakers, fuses and converter are new together
- Detects a lithium battery on its own, so a LiFePO4 upgrade needs no settings
- Fan speeds up only with load, so it stays quiet overnight on light draws
- Enough output to run lights, fans and the furnace while still charging
Cons
- Two year warranty
- Replacing a full panel means rewiring every AC and DC circuit, a job for a technician
