Reading the specifications

Dyness 35kWh High Voltage Battery with BDU is listed with 9 published specifications from Dyness, including cooling method of Natural Cooling, battery chemistry of Lithium Iron Phosphate (LiFePO₄ / LFP), battery type of High Voltage Energy Storage Battery and communication of CAN, RS485. Those figures are what decide whether this unit fits your system, so read them against the equipment it will connect to before comparing price.

For a battery, the figures that matter most are nominal capacity in ampere-hours (Ah) or kilowatt-hours (kWh), usable capacity after depth of discharge — LiFePO4 typically allows 80–100%, lead-acid closer to 50%, system voltage: 12 V, 24 V and 48 V for low-voltage packs, or a high-voltage stack and continuous charge and discharge current, which limits how much power you can draw from the pack. Storage is what turns a solar array from a daytime bill-reducer into a system that covers evening loads and rides through outages. It is normally the single most expensive component, so sizing it correctly matters more than with any other part.

Choosing a battery: the checks that matter

The checks below apply to any battery. Run them against the specification table above — most disappointing solar purchases are compatible-on-paper units that fail one of these in practice.

Check the continuous discharge rating against your inverter. A battery that stores plenty of energy but can only deliver 50 A cannot support a large inverter at full output.
Match voltage to the inverter, and confirm the battery appears on the inverter maker's supported list. Closed-loop communication lets the inverter respect the battery's real charge limits instead of guessing.
Read the warranty in full: lithium warranties are stated as a term plus either a cycle count or a total energy throughput, and whichever limit arrives first ends the cover.
Leave room to expand. Packs that parallel cleanly let you add capacity later; ones that do not force a full replacement.

Common mistakes

Sizing the bank for total daily consumption rather than after-dark consumption, which typically doubles the cost for no benefit.
Installing lithium packs in an unventilated, hot enclosure. Sustained high temperature is the fastest way to lose cycle life.
Ignoring the charge current limit and pairing a large array with a small bank, which trips protection and shortens life.

Price and availability

No price is published for Dyness 35kWh High Voltage Battery with BDU at the moment. Pricing on solar equipment moves with supply and exchange rates, and some distributors quote only on request — the specifications above are still directly comparable against alternatives that do list a price.

SolarBazaar compares equipment rather than selling it. Shortlist here on specification and price, then buy from an authorised distributor or installer in your country: warranty cover on solar hardware is normally honoured through the channel you bought from, so confirm who supports Dyness locally before ordering.

Dyness 35kWh High Voltage Battery with BDU — frequently asked questions

What are the specifications of Dyness 35kWh High Voltage Battery with BDU?

We hold 9 published specifications for this battery, including cooling method Natural Cooling, battery chemistry Lithium Iron Phosphate (LiFePO₄ / LFP), battery type High Voltage Energy Storage Battery, communication CAN, RS485 and installation Floor Standing / Stackable. The full table is on this page, listed under model DYNS-14.

Who makes Dyness 35kWh High Voltage Battery with BDU?

Dyness 35kWh High Voltage Battery with BDU is a Dyness product, listed under batteries with model reference DYNS-14. The Dyness brand page lists the rest of its range so you can compare across the catalogue.

Is Dyness 35kWh High Voltage Battery with BDU right for my system?

That depends on what it has to connect to. For a battery, check continuous charge and discharge current, which limits how much power you can draw from the pack, cycle life at a stated depth of discharge, commonly 3,000–6,000 cycles for LiFePO4 and round-trip efficiency, around 90–95% for lithium and 75–85% for lead-acid against the rest of your equipment before price enters the decision. Match voltage to the inverter, and confirm the battery appears on the inverter maker's supported list. Closed-loop communication lets the inverter respect the battery's real charge limits instead of guessing.

Where can I buy Dyness 35kWh High Voltage Battery with BDU?

SolarBazaar lists and compares equipment rather than selling it. Use the specifications and price here to shortlist, then buy through an authorised distributor or installer — buying in-channel is what keeps the manufacturer's warranty valid.
