Обзор продукции
CHAC CQHD PV combiner box integrates DC circuit-breaker protection with PV string combining, surge protection and fuse components. Select the exact input/output model: the voltage, breaker current and maximum output current are not identical across all versions.
Для импортёров, дистрибьюторов и производителей оборудования компания CHAC может провести проверку заявленной конфигурации в соответствии с требованиями электрической цепи и документами рынка назначения. Уточните точную модель, чертежи и требования к маркировке до утверждения образца или размещения повторного заказа.
Ключевые моменты отбора
Типичные применения
Evaluate CQHD for PV DC assemblies requiring the specified breaker-based protection arrangement. Use the inverter input limits, PV string design and assembly drawing to choose the box rather than selecting only by enclosure size or string count.
Приложение и руководство по отбору
| Элемент выбора | CQHD configuration | Что нужно проверить |
|---|---|---|
| Выбор ввода/вывода | 1/1, 2/1, 3/1, 2/2, 4/2 или 6/2 | Confirm which strings feed each output and the inverter arrangement. |
| Voltage options | 500V / 1000V DC according to model | Some variants list only 1000V; confirm the exact version. |
| Breaker current | 16A / 32A / 45A according to model | This is distinct from the listed 32A / 63A maximum output rating. |
| Защита | PC; IP65 / IK09; wall mounting | Confirm gland selection, sealing and service space for the actual installation. |
Use these checks to compare the protection function, configuration and related CHAC products before specifying CQHD. Related products are selection alternatives or system components, not automatic replacements.
Do not confuse breaker current with maximum output current
The CQHD tables list both values.
Approve the string grouping and protection together
Select the voltage version, input/output layout, fuse links, DC breaker and SPD as a coordinated assembly.
Review CQHS in the PV system
The CHAC CQHS PV DC combiner box combines photovoltaic string inputs with a DC isolator for DC-side disconnection. Choose from six input/output configurations to match your PV array layout, and confirm the voltage and current ratings for the selected model.
Review CQBD-63 in the PV system
Выключатель постоянного тока CHAC CQBD-63 обеспечивает защиту от перегрузки и короткого замыкания, отличается неполярной конструкцией и индикацией положения контактов. Одно- и четырёхполюсные версии рассчитаны на напряжения постоянного тока от 300V до 1200V; подберите количество полюсов и характеристику срабатывания в соответствии с цепью.
Need Help Specifying CQHD?
Отправьте требования к схеме, выбранный вариант конфигурации, целевой рынок и количество для проведения проверки по конкретной модели.
Do not confuse breaker current with maximum output current
The CQHD tables list both values. For example, the 2/1 configuration lists a 32A DC breaker and a 63A maximum output current. That does not authorize continuous operation at 63A through the 32A breaker. Confirm the limiting component and the complete assembly duty.
Approve the string grouping and protection together
Select the voltage version, input/output layout, fuse links, DC breaker and SPD as a coordinated assembly. Compare maximum string voltage and current with the inverter input requirements, and obtain the exact drawing before installation or repeat procurement.

CQHD Product FAQ
How many PV strings can a CQHD box combine?
The series lists 1/1, 2/1, 3/1, 2/2, 4/2 and 6/2 input/output configurations. Confirm the internal grouping and inverter compatibility for the exact model; the total input count alone does not determine the MPPT arrangement.
Can a 63A maximum output rating override a 32A breaker rating?
No. The installed protective device and the other assembly limits still apply. Where a CQHD table lists a 32A breaker and 63A maximum output, confirm the intended duty; do not treat 63A as an authorized continuous current through that breaker.
Can I use any CQHD box at 1000V DC?
Order the voltage version documented for the exact model and confirm all installed components and wiring. Do not assume that a 500V version becomes a 1000V assembly because another version has that rating.
How should the PV string fuse be selected?
Check string current, reverse-current exposure, module maximum series-fuse rating and local rules. Confirm the fuse-link part number and rating in the CQHD assembly schedule. Do not select a fuse solely from the fuse holder’s maximum current.
Does the CQHD enclosure rating cover any outdoor installation?
No enclosure rating removes the need to assess exposure, temperature, cable entries, sealing and mounting. Preserve the specified IP65 construction during installation and confirm any site conditions outside the approved assembly requirements.
What information is needed to quote a CQHD box?
Provide string count and grouping, maximum PV voltage, string current, inverter model and MPPT inputs, required protection, cable details, site conditions, quantity and destination market. Agree the drawing and component schedule before production.
Specify the Right CQHD Configuration
Send CHAC your required configuration, application, destination market and estimated quantity. We will review the requested specification and provide the relevant technical documents and commercial proposal.
