What it does well
- A 10-year warranty as standard, with no registration step needed to reach it.
- 9.216 kWh usable in a single wall-mounted unit, roughly double a Pylontech US5000 module, so fewer units for the same storage.
- Named Philippine distributors, so there is a local party behind a claim.
Where it falls short
- The warranty is throughput-based, not purely calendar — cycle it hard and it can expire before ten years are up, which a brochure figure will not tell you.
- Depth of discharge and stacking limits differ across the Powerbox, Powerbox Pro and Powerbox G2 generations, so confirm exactly which one you are quoted.
- At 90% the Pro's depth of discharge is below the 95% Pylontech offers on its newer modules.

Dashes are figures the manufacturer does not publish, not zeros. Where two products differ on a spec, which one matters depends on your roof and your usage — a higher efficiency panel earns its premium on a small roof and rarely on a large one.
Dyness is a Chinese LiFePO4 battery maker (founded 2017) that’s carved out a budget-to-mid-tier spot in stackable, low-voltage home batteries. The specs on paper are competitive with Pylontech and BYD at a lower price, but the brand also has a recurring pattern of independent user complaints abroad about overheating and BMS behavior that’s worth reading before you buy — this isn’t a case of a spotless product with a thin channel, it’s a reasonably good product with a real reliability question mark.
Lineup and specs
Dyness’s home range is low-voltage and stackable, built to pair with mainstream hybrid inverters rather than as an all-in-one system. The PowerBox Pro (10.24 kWh) and DL5.0C (5.12 kWh) are the current residential modules, alongside the older B-Box line that’s still in circulation. Dyness rates round-trip efficiency around 95% and claims 6,000+ cycles on its newer product lines, which is in the same range as Pylontech and BYD. Depth of discharge and stacking limits vary by model, so confirm the exact datasheet for the module you’re quoted rather than assuming the flagship figures apply across the whole range.
Warranty
Dyness backs its batteries with a 10-year warranty, but it’s throughput- based (tied to total energy cycled, not just a calendar term) and guarantees 70% capacity retention at the end of that period — broadly comparable to what Pylontech and BYD publish, on paper.
Local availability
Photonergy Inc. distributes Dyness in the Philippines under the “Dyness Philippines” name, based in Antipolo, and the brand also shows up in scattered Lazada listings. That’s a real, findable channel, but it’s thin compared to Pylontech’s or BYD’s installer footprint — fewer companies have actually wired a Dyness stack before, and fewer have spare modules or BMS units sitting on a shelf.
What a Dyness battery costs in the Philippines
We don’t quote a single marketplace sticker price, because none is stable enough across the distributor and Lazada listings to be reliable. What we can ground is the installed cost, which is the number that actually matters. Home solar batteries in the Philippines run roughly ₱13,000-23,000 per usable kWh installed — the basis for that figure is in our solar battery price guide. Applied to Dyness’s current modules:
| Dyness module | Capacity | Rough installed range |
|---|---|---|
| DL5.0C | 5.12 kWh | ₱65,000-120,000 |
| PowerBox Pro | 10.24 kWh | ₱130,000-235,000 |
Dyness sits at the budget end, so expect real quotes toward the lower side of each band for the battery itself. Two things move the final number more than the brand: whether your inverter can charge a battery at all — a plain grid-tied unit can’t, and adding a hybrid one is ₱25,000-150,000 depending on tier on top — and the installer’s labour and protection. Get an itemized quote from Photonergy or your installer for the exact figure, and compare it on peso per usable kWh rather than sticker price.
Where it falls short
This is the part to take seriously. Independent complaints on forums like the Victron community, DIY Solar Power forum, and PowerForum recur often enough to be a pattern rather than isolated incidents: users reporting overheating and thermal shutdowns under load, a BMS bug that limits charging below expected levels, state-of-charge readings that jump or drift instead of tracking smoothly, and weak response from Dyness’s own warranty and support channels when something goes wrong. Several users also reported that modules purchased at different times weren’t fully compatible when stacked together — worth asking your installer to confirm in writing if you’re expanding an existing bank rather than buying a full stack new. None of this means the battery is unsafe or broadly defective, but it does mean the support and reliability track record is the real risk here, not the underlying spec sheet.
Who it’s best for
Budget-conscious buyers who want genuine LFP chemistry at a price below Pylontech and BYD, are working with an installer willing to vouch for the brand from direct experience, and are going in with realistic expectations about a thinner support channel if something needs warranty service down the line. If installer-network depth and support track record matter more to you than shaving pesos off the sticker price, Pylontech or BYD remain the safer default.
