6KW Hybrid Solar DB Bundle with Plastic Body for Single PV Sting

6KW Hybrid Solar DB Bundle Plastic Body (Single PV String) is a hybrid solar DB bundle for Pakistan that protects the solar side, load side, and battery-ready switching side more intelligently than a basic on-grid board. Starting from Rs.10,775, it is designed for buyers in Lahore, Karachi, Islamabad, Rawalpindi, Faisalabad, and Peshawar who want a safer solar installation for homes facing load shedding, voltage fluctuation, and daily battery backup use.

What’s Inside This Bundle

CNC Bundles vs Competitors

Missing DC SPD in a solar installation means a single lightning-related surge can destroy a Rs.200,000-500,000 inverter. CNC bundles include matched, tested components with warranty coverage — not loose parts from mixed brands.

Compatible Inverters

This bundle's DC protection is rated for 600V DC hybrid systems. It is compatible with:

• Knox Krypton 4.5-10kW (max 500V DC)
• Inverex Nitrox 6-8kW (max 500V DC)
• Sungrow SH3-10RS hybrid (max 600V DC)
• GoodWe ES/ES G2 hybrid (max 600V DC)
• Growatt SPH/SPF hybrid (max 550V DC)
• MaxPower Sunbridge series

For three-phase on-grid inverters like Huawei or Fronius (max 1,000-1,100V DC), see our on-grid solar DB bundles which use 1000V-rated DC protection.

What This Product Does

6kW hybrid with single PV string input. Same price as 3kW plastic because single string = fewer DC components. For homes running 1-2 ACs, fridge, lights, fans, pump. Single PV string means all panels in series — simpler wiring. CNC Electric Pakistan positions hybrid bundles differently from plain on-grid bundles because a hybrid installation does not only push daytime solar to loads. It also has to coordinate inverter behavior, stored battery energy, and critical home circuits when WAPDA power disappears.

A 6kW hybrid system is a very practical range for Pakistani families that want solar generation in the day and battery-backed essential loads at night. That is why hybrid bundles are attractive to homeowners who want more than daytime bill reduction. They want evening continuity for selected loads such as lights, fans, internet, fridge, a water pump, or one to two ACs depending on system size and battery bank design.

Compared with buying individual DC breakers, DC SPDs, MCBs, and enclosure parts separately, a bundle reduces confusion and makes the protection logic easier to understand. It also creates a cleaner path for electricians and solar installers who want a more professional result than a patchwork board.

Hybrid Solar DB vs On-Grid Solar DB

Many Pakistani buyers search solar DB bundle and assume every bundle does the same job. It does not. An on-grid solar DB mainly focuses on panel-side and AC-side protection for a system that follows the grid. A hybrid solar DB bundle is more relevant when the solar inverter also manages battery charging and backup load continuity during load shedding.

In simple words, on-grid is about safe solar generation and grid interaction. Hybrid is about safe solar generation plus backup behavior. That is why hybrid buyers should think about battery-side isolation, protection coordination, correct breaker selection, surge control, and future maintenance access. For many homes in Pakistan, hybrid gives peace of mind because it matches real daily conditions better than a pure grid-only setup.

Body Material and PV String Strategy

The enclosure and PV string design change the real-world value of the bundle. Plastic body enclosure affects durability, weight, corrosion comfort, installation environment, and buyer confidence. Plastic can be lighter and more economical. Steel usually feels stronger and more premium in demanding locations. Neither choice is automatically right for every site; the best choice depends on budget, environment, and how rough the installation conditions are.

PV string architecture matters just as much. A single-string setup is simpler and usually cheaper because it needs fewer DC protection points. A double-string setup is valuable where panels are split across two roof faces or separate layouts. More strings usually mean more flexibility, but they also mean more hardware and more protection complexity.

Selection Guide

What Is Usually Inside a Hybrid Bundle

How to Install

• Mount the bundle enclosure on a suitable wall location away from avoidable moisture and random heat sources.
• Use a licensed electrician or solar installer to connect the PV side, inverter side, and battery-related paths correctly.
• Confirm all breaker ratings, cable sizes, and polarity before energizing the system.
• Test the DC side, AC side, and backup behavior under controlled commissioning conditions.
• Label circuits clearly so future maintenance does not become a guessing game.

What This Product Does NOT Protect Against

This hybrid solar DB bundle does not eliminate the need for correct earthing, proper cable sizing, and skilled installation. It does not replace a dedicated voltage protector where sustained overvoltage or undervoltage is expected on the AC side. It also does not replace every battery-specific protection requirement in every custom system design. For lightning and surge issues, a dedicated DC SPD or AC SPD remains part of the protection story. For overload and short-circuit behavior on final load circuits, you still need correctly chosen MCBs or RCBO / RCCB devices where relevant.

Cross-Category Recommendations

If you are buying this hybrid bundle, also review AC circuit breakers, DC circuit breakers, AC breaker collection, DC breaker collection, MCCBs, AC SPDs, DC SPDs, voltage protectors, voltage regulators / stabilizers, RCCB / RCBO, types of circuit breakers, MCB size chart for Pakistan, trip curves explained, SPD full form guide, voltage protector vs stabilizer. Hybrid buyers should particularly understand the difference between solar DB design and pure on-grid protection, because battery-backed systems add another layer of design thinking. It is also smart to review voltage protector vs stabilizer and SPD guidance before finalizing a solar protection budget.

FAQs

What is the difference between a hybrid solar DB and an on-grid solar DB?

A hybrid solar DB bundle is more relevant when the inverter also manages batteries and backup loads. An on-grid bundle is more focused on grid-tied daytime generation without the same battery-backup logic.

Why is this hybrid bundle useful in Pakistan?

Because load shedding, voltage fluctuation, and battery backup needs make hybrid systems very practical in Pakistan. Buyers in Lahore, Karachi, Islamabad, Rawalpindi, Faisalabad, and Peshawar often want both solar generation and backup confidence.

Is plastic body enclosure better than the other option?

Plastic body enclosure is not automatically better for every site. The decision depends on budget, environment, physical handling expectations, and whether the buyer values lighter cost savings or a stronger-feeling enclosure.

What does single PV string or double PV string mean?

Single PV string usually means one simpler series path of panels. Double PV string means two separate strings, which is helpful when roof layout, orientation, or design flexibility requires separate DC protection paths.

Can this bundle run ACs, geyser, fridge, washing machine, and pumps?

That depends on total system size, inverter capacity, battery bank, load management, and how the installer divides critical and non-critical circuits. Hybrid systems can support priority appliances, but exact behavior should always be planned by a qualified installer.

Does this bundle include surge protection and voltage protection automatically?

A bundle improves the protection path, but the buyer should still confirm exactly which AC-side, DC-side, and voltage-protection components are part of the selected tier. That is why comparing related products is important before checkout.

Why should I buy a bundled hybrid DB instead of separate parts?

A bundled approach reduces confusion, helps align compatible protection logic, keeps the panel neater, and saves time for the installer. It is also easier to compare tiers and budgets when everything is grouped logically.

Is this available with free delivery and warranty?

Yes. CNC Electric Pakistan offers free delivery across Pakistan and a 5-year warranty, which is a major trust point when buyers compare against mixed local market options.

Can my electrician install this or do I need a solar specialist?

A licensed electrician or qualified solar installer should install and commission the bundle. Hybrid systems combine AC, DC, and battery-related logic, so random trial-and-error installation is not a good idea.
