Puntos clave de selección
Aplicaciones típicas
Consider CQHS for residential or commercial PV DC assemblies where the design calls for an isolator-based combiner. Confirm the string grouping and protective-device schedule with the inverter requirements before approving the assembly.
Guía de Solicitudes y Selección
| Elemento de selección | CQHS configuration | Qué verificar |
|---|---|---|
| Input/output choice | 1/1, 2/1, 3/1, 2/2, 4/2 or 6/2 | Confirm the wiring and MPPT grouping for the exact model. |
| Series ratings | 1000V DC; maximum output current 32A as specified | Check the exact output duty and component limits; do not select by total array power alone. |
| Main switching device | CQDS-32 DC isolator | Distinguish isolation from automatic breaker protection. |
| Recinto | PC; IP65 / IK09; wall mounting | Match cable glands, sealing, mounting position and service access to the installation. |
Use these checks to compare the protection function, configuration and related CHAC products before specifying CQHS. Related products are selection alternatives or system components, not automatic replacements.
Keep separate MPPT circuits separate
Two outputs do not automatically establish any particular internal MPPT grouping.
Confirm the component schedule for the selected box
The component information identifies the CQDS-32 isolator, CQDF-32 fuse holder and ExS-T2-DC SPD.
Review CQHD in the PV system
The CHAC CQHD PV DC combiner box combines photovoltaic string inputs with DC circuit-breaker protection. Choose from six input/output configurations to match your PV array layout, and confirm the voltage and current ratings for the selected model.
Review CQDS-32 in the PV system
The CHAC CQDS-32 photovoltaic DC isolation switch provides isolation and infrequent switching between PV modules and inverters. Its non-polar design supports selected DC-PV1/DC-PV2 configurations up to 1200V DC and 32A; follow the wiring arrangement specified for the chosen configuration.
Need Help Specifying CQHS?
Send the circuit requirements, selected configuration, destination market and quantity for a model-specific review.
Keep separate MPPT circuits separate
Two outputs do not automatically establish any particular internal MPPT grouping. Provide the inverter input arrangement and string plan, then approve the exact CQHS wiring diagram. Do not combine strings that the inverter design requires to remain separate.
Confirm the component schedule for the selected box
The component information identifies the CQDS-32 isolator, CQDF-32 fuse holder and ExS-T2-DC SPD. Confirm the actual fuse links, SPD version, voltage and current limits for the ordered assembly. Component maximum ratings do not automatically become the assembled box rating.

CQHS Product FAQ
How do I size a solar combiner box?
Start with the number of strings and inverter inputs, then check cold-condition open-circuit voltage, string current, protection requirements and output limits. Choose the exact CQHS input/output configuration and approve its wiring diagram.
What is the difference between CQHS and CQHD?
CQHS uses a DC isolator, while CQHD uses a DC circuit breaker as the main switching/protection element. Compare the exact box ratings and component schedule; the two series are not automatic substitutes.
Does a two-output combiner automatically support two independent MPPTs?
Not solely from the output count. Confirm the internal circuit grouping, both conductor paths and the inverter requirements using the exact assembly drawing. Avoid joining circuits intended for separate MPPT channels.
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 CQHS assembly schedule. Do not select a fuse solely from the fuse holder’s maximum current.
Does the CQHS 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 CQHS 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 CQHS 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.
