Maximum module efficiency of the family

dhm54d35-450-tp

What we publish

The datasheet states the maximum module efficiency of this family as 22.52% on its summary page and 23.02% on its specification page. We do not publish either figure as the family maximum. The efficiency of the 450 W module we stock is stated as 22.52% in the STC table, and that is the figure we use.

Maximum module efficiency of the family

dhm66d60-630-tp

What we publish

The datasheet header states the highest component conversion efficiency as 23.14%, while its own STC table gives 23.51% for the 635 W model — 23.14% is in fact the 625 W figure. We publish neither as the family maximum. The 630 W module we stock is stated as 23.32% in the STC table, and that is the figure we use.

Power range of the DHM54D35-TP family

dhm54d35-450-tp

What we publish

The dedicated datasheet covers 435-460 W and the company catalogue covers 425-450 W for the same family name. The 450 W module we stock appears in both, with identical electrical values, so the module itself is not in doubt — only the family range is.

Power range of the DHM66D60-TP family

dhm66d60-610-tp

What we publish

The dedicated datasheet covers 610-635 W and the company catalogue covers 585-610 W under the same family name. The two documents also state the efficiency of the 610 W model differently: 22.58% and 22.56%. The 630 W module we hold in the deepest quantity appears only in the datasheet.

Power range of the DHM66D50-TP family

dhm66d50-720-tp

What we publish

The dedicated datasheet covers 690-720 W and the catalogue 695-720 W. The 720 W module we stock is at the top of both ranges and its electrical values agree in both documents.

Frame depth of the stocked lots

dhm66d60-610-tp

What we publish

The warehouse rows describe these lots as having a 35 mm frame; the dedicated datasheet documents a 30 mm frame. Mounting clamps are sized to the frame, so the physical frame must be measured at the warehouse before rails and clamps are ordered.

DS60, p. 2 · PL, p. 1

Frame depth of the 35 mm lot

dhm66d60-630-tp

What we publish

One of the three stocked lots is described with a 35 mm frame while the datasheet documents 30 mm. The other two lots are described as 30 mm and match the datasheet. Frame depth must be measured before clamps are ordered for the 35 mm lot.

Warranty term

dhlv-lfp-5000

What we publish

The datasheet headline says "10 years (5 free warranty + 5 paid warranty)". No written warranty terms have been supplied: no conditions, no exclusions, no throughput or cycle limit, and no named warranty provider. We do not publish a warranty term as a commitment.

DS5K, p. 2

Warranty term

dh-wll010d1

What we publish

The datasheet states "10 years" with no conditions, no exclusions, no cycle or throughput limit and no named warranty provider. We do not publish a warranty term as a commitment.

DS10K, p. 2

Warranty term

dh-314t16r

What we publish

The datasheet states "10 years" with no conditions, no exclusions and no named warranty provider — and this sheet names a different company as reserving interpretation. We do not publish a warranty term as a commitment.

DS16K, p. 2

Module warranty

dhm54d35-450-tp

What we publish

The datasheets carry 30-year power output and 25-year product warranty badges and a degradation curve, but no written warranty terms have been supplied: no conditions, no exclusions, no claims process and no named warranty provider for Ukraine. We do not publish a warranty term as a commitment.

Certificates listed by the manufacturer

dhlv-lfp-5000

What we publish

The two pages of the same document list different certificate sets, and neither is a certificate. We publish no certification list. A copy of the valid certificate for the buyer market is supplied on request before any commercial commitment.

Certificates listed by the manufacturer

dh-wll010d1

What we publish

The two pages of the same document list different certificate sets, and neither is a certificate. We publish no certification list.

DS10K, p. 1 · DS10K, p. 2

Certificates listed by the manufacturer

dh-314t16r

What we publish

The datasheet lists CE, UN38.3 and MSDS — a shorter list than the other two batteries, and notably without IEC 62619. A listed standard name is not a certificate. We publish no certification list.

DS16K, p. 2

Module certification evidence

dhm54d35-450-tp

What we publish

The documents list different standard sets for the same modules, and different ISO revision years — one page cites ISO 9001:2008 and ISO 14001:2004, another ISO 9001:2015 and ISO 14001:2015. A logo on a brochure and a standard name in a list are not certificates. We publish no certification list and no certificate claim. A copy of the valid certificate for the buyer market is supplied on request before any commercial commitment.

Price difference between the configurations with and without the 125 kW PCS

dh261l-125k-with-pcs

What we publish

The price list shows only a USD 2,000 difference between the configuration that includes a 125 kW power conversion system and the one that does not. A 125 kW PCS is not a USD 2,000 component. Either the price list is wrong, or the two rows do not mean what their labels suggest. No price or configuration statement is published for either row until this is resolved.

PL, p. 1 · PL, p. 1

What the configuration without a PCS contains

dh261l-without-pcs

What we publish

No datasheet in our document set describes a 261 kWh cabinet supplied without the 125 kW PCS. The AC-side figures on the cabinet datasheet belong to the PCS and therefore do not apply to this configuration. What is included, and what the buyer must supply, has to be confirmed with the supplier before quotation.

PL, p. 1 · DSC, p. 1

Weight

dhm66d60-610-tp

What we publish

The dedicated datasheet states 33 kg and the company catalogue states 33.5 kg for the same module. We do not publish a weight for this family. Plan structural and handling calculations on the higher figure until DAHAI confirms.

DS60, p. 2 · CAT, p. 13

Temperature coefficient of Pmax

dhm66d60-610-tp

What we publish

The datasheet states −0.290 %/°C and the catalogue −0.30 %/°C. We do not publish a temperature coefficient for this family; a yield model should use the less favourable figure.

DS60, p. 2 · CAT, p. 13

Maximum fuse current rating

dhm66d50-720-tp

What we publish

The dedicated datasheet states 30 A and the company catalogue 35 A for the same module. Because the lower figure is the safe one for string protection design, no fuse rating is published for this model until DAHAI confirms.

DS50, p. 2 · CAT, p. 11

Frame and cable of the stocked lot

dhm66d50-720-tp

What we publish

The only description on the price list for this model belongs to the row with zero stock, which specifies a 0.5 m cable. The row with 216 units in stock has no description at all. We do not assume the two are the same configuration: a 0.5 m cable and a 1.4 m cable are different products to install.

PL, p. 1 · PL, p. 1

Low-temperature heating function

dh-wll010d1

What we publish

The specification table lists electric heating as present but the 130 W heating film as optional, while the marketing page presents the heating function as a capability of the product. Whether the units in Lviv carry the heating film is not established, so no low-temperature operating claim is published for them.

DS10K, p. 2 · DS10K, p. 1

Storage temperature range

dh-314t16r

What we publish

The storage-temperature row of the datasheet carries a humidity expression, "@60+25% Relative Humidity", that does not parse and does not match the humidity row directly below it. We publish no storage temperature range for this model.

DS16K, p. 2 · DS16K, p. 2

Legal manufacturer

dh-314t16r

What we publish

This datasheet names Jiangsu SolarEast Energy Storage Technology Co., Ltd. where the other DAHAI battery sheets name Dahai Solar. Who the legal manufacturer is matters for warranty, customs paperwork and conformity documentation, so we publish neither name as the manufacturer of this model.

DS16K, p. 2 · DS10K, p. 2

Maximum number of packs

dh-shl005ra1

What we publish

The marketing page claims scalability to 56 packs while the specification table on the next page stops at five packs in series and eight parallel strings. We publish no maximum pack count.
