Pylontech Fidus series
| Model | Usable Capacity | Dimensions (W×D×H) | Weight | Continuous Charge/Discharge | Cycle Life |
|---|---|---|---|---|---|
| Fidus 5.12 kWh (FB-L-5.12-PK) | 4.97 kWh (97% DoD) | ~630×170×363 mm | ~45 kg | 100 A (121–200 A peak, 15s) | 8,000+ cycles / 10-yr warranty |
| Fidus Plus 16 kWh (FB-L-16-PK) | 16.08 kWh (100% DoD) | 435×240×900 mm | ~130 kg | 180–200 A (300 A peak) | 8,000 cycles / 10-yr warranty |
Both Fidus models run on a 51.2V nominal system, communicate over CAN/RS485, and carry up to a 15-year design life. The 5.12 kWh module can be wall- or rack-mounted; the 16 kWh Fidus Plus is a single floor-standing or wall-mounted vertical enclosure rather than a stack of smaller modules. Dimensions and weight vary slightly between the IP20 indoor and IP65 outdoor variants — confirm which version is being quoted.
Dyness DL5.0F & PowerBrick Max
| Model | Usable Capacity | Dimensions (W×D×H) | Weight | Continuous Charge/Discharge | Cycle Life |
|---|---|---|---|---|---|
| DL5.0F 5.12 kWh | ~4.87 kWh (95% DoD) | 488×515×150 mm | 41 kg | 100 A max | 8,000 cycles / 10-yr warranty |
| PowerBrick Max 16.076 kWh | 15.27 kWh (95% DoD) | 435×233×857 mm | 116 kg | 140 A rec. / 200 A max (300 A peak, 2 min) | 8,000+ cycles / 10-yr warranty |
Both run at 51.2V nominal and communicate over CAN/RS485. The DL5.0F scales up to 50 units in parallel; the PowerBrick Max scales the same way up to roughly 803 kWh. Both are compatible with GoodWe, SMA, Victron, Growatt, Deye, Solis and other major hybrid inverter brands — always check the current Dyness compatibility list for your specific inverter model.
Which one fits your situation?
- Entry-level 5 kWh system: the Fidus 5.12 kWh and DL5.0F are closely matched — both around 5 kWh usable, 8,000-cycle rated, 10-year warranty, and compact enough for a wall or rack. The Fidus is somewhat heavier (~45 kg vs 41 kg) but rated for a higher peak surge current (up to 200 A vs the DL5.0F's 100 A max).
- Single-unit 16 kWh system: the PowerBrick Max is lighter (116 kg vs ~130 kg) and rated for a higher continuous current (200 A vs 180–200 A) than the Fidus Plus, and both carry a 10-year warranty at this capacity.
- Want to add capacity gradually: starting with 5 kWh modules (Fidus or DL5.0F) and adding more later is more flexible than committing to a single 16 kWh unit upfront.
- Floor space vs wall space: the 16 kWh units from both brands are floor-standing; if you only have wall space, the 5 kWh modules are the practical option.
Both brands are solid, current-generation options — the right choice depends on your available space, your backup hours needed, and whether you plan to expand later. We size and quote both options side-by-side as part of every proposal, based on a free site survey.
