- Replaces the whole WF-8700-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
- Low price for a complete panel
- Two year warranty
- Replacing a full panel means rewiring every AC and DC circuit, a job for a technician
- 35 A charges a large lithium bank slowly
