Solar Inverters for Installation Companies

sun.store is a professional B2B marketplace built for contractors who need to move quickly from design to delivery. Here you can compare solar inverters side-by-side, check transparent stock across multiple suppliers, and buy solar inverter models that match your bill of materials without chasing quotes across inboxes. Filters for phase, power class, MPPT count, communications, and inverter warranty terms keep your shortlists tight and relevant.

Because we aggregate listings for the same PV inverter from more than one solar inverter supplier, you see multi-vendor availability at a glance. That reduces procurement risk, streamlines approvals, and helps you keep crews scheduled. Product pages include inverter datasheet links, so you can validate inverter certifications, I/O ratings, and inverter safety features before you commit.

If you’re building mixed carts (e.g., residential solar inverters plus mid-range commercial solar inverters), consolidated checkout and coordinated dispatch keep projects on track. Browse in-stock options, compare solar inverters, and request a tailored quote when you need pallet or container quantities.

Inverter Technologies and System Types

Select the right solar inverter by mapping technology to use case, site constraints, and code requirements. The notes below focus on practical design levers you’ll actually use in the field.

On-grid Inverters

An on-grid inverter converts DC from solar panels to AC that synchronizes with the utility grid for export or self-consumption. It’s the staple choice for residential rooftops and small commercial up to multi-hundred-kW systems. Prioritize wide input voltage windows and adequate max PV input current for cold-weather margins. Check grid compliance (e.g., regional grid codes) and reactive power settings to avoid commissioning delays.

Off-grid Inverters

An off-grid inverter serves stand-alone systems with generator support or remote loads. Typical use cases include cabins, telecom sites, and microgrids from a few kW upward. Battery charging and transfer switch behavior matter; verify surge capacity and AC passthrough ratings. Look for models with robust protection device integration and clear inverter monitoring of SOC when paired with solar batteries.

Hybrid Inverters

A hybrid inverter handles PV and storage in one chassis, simplifying wiring and control. Ideal for self-consumption, backup, and TOU shifting in homes and light commercial. Confirm DC-coupled battery support, charge/discharge current, and backup output power. Pay attention to inverter efficiency both in PV mode and round-trip when storage is active.

Microinverters

A microinverter sits behind each module, maximizing yield on complex roofs with partial shading and multiple azimuths. Typical arrays range from a few to a few dozen modules; scaling to larger sites is possible with trunk cabling. Selection hinges on module current compatibility and rooftop temperature derating. Ensure gateway inverter monitoring coverage and grid compliance for your market.

Three-phase Inverters

A three-phase inverter is standard for commercial rooftops, C&I ground mounts, and larger homes with 3-phase service. Expect power classes from 10 kW to >100 kW. Specify enough MPPTs and string inputs for layout flexibility, especially with mixed tilts. Reactive power control and THD performance influence interconnection approvals and operational stability.

Single-phase Inverters

A single-phase inverter is common in residential and small light-commercial sites. Sizes typically range from 1–10 kW. Verify input current per string against modern high-current modules and ensure inverter warranty terms meet client expectations. If backup is planned later, consider models compatible with solar batteries or AC-coupled storage.

Top Technical Features That Set Inverters Apart

Focus on inverter features that materially affect design, commissioning, and O&M:
- Input voltage range & max PV input current: Supports long strings and high-current modules; enables cold-weather margins without tripping start-up thresholds.
- Number of MPPTs & string inputs: More MPPTs improve layout flexibility with multiple roof facets and partial shading; confirm parallel string current limits and fusing.
- Max efficiency / EU efficiency: Higher inverter efficiency improves lifetime yield; small deltas matter in C&I fleets.
- Grid compliance & reactive power control: Built-in volt/var and frequency-watt functions streamline interconnection and commissioning success.
- Battery compatibility: For a hybrid inverter, check DC-coupling vs AC-coupling, supported battery protocols, and charge/discharge current.
- Built-in protections: AFCI (arc-fault), SPD Type II/III, RCD options, rapid shutdown (where required) – the right protection device set reduces call-outs.
- Communication & monitoring: RS485/Ethernet/Wi-Fi/4G, app/portal access, and APIs for fleet tools; verify gateway limits for inverter monitoring.
- Enclosure & durability: IP rating (e.g., IP65), cooling topology (natural vs forced), and derating behavior at high ambient temperatures.
- Warranty & service: Standard terms, extension options, RMA/swap programs, and regional service centers—critical inverter warranty considerations.

Solutions for Installation Professionals

Procurement should match the pace of your crews. On sun.store you can place bulk orders, request custom quotes for multi-site rollouts, or build mixed-brand carts when availability dictates. We coordinate pallet and container deliveries to your jobsite timeline and provide tracking so you can plan lifts and labor.

Every solar inverter for sale includes linked documentation, from the inverter datasheet to manuals, certifications, and wiring diagrams where provided by the manufacturer. If you’re bidding a portfolio, use our filters to shortlist on-grid inverter, off-grid inverter, hybrid inverter, microinverter, three-phase inverter, or single-phase inverter models by MPPT count, communications, and inverter warranty. When a model is listed by multiple sellers, you’ll see that at a glance—making it faster to compare solar inverters and secure the quantities you need.

For C&I, you can align PV inverter selections to site-specific grid compliance requirements and confirm reactive power settings before the truck rolls. Our team can clarify feature differences during selection (e.g., inverter monitoring options or inverter safety features) so you avoid surprises at commissioning.

Certifications and Safety Standards

Compliance is a prerequisite for approvals, insurance, and warranty validity. Look for inverter certifications such as IEC 62109 (safety of power converters) and regional grid codes like EN 50549 for parallel operation, plus country-specific requirements where applicable. Choosing certified inverters simplifies DNO/DSO paperwork and reduces rework.

Safety isn’t only paperwork. Modern solar inverters include arc-fault detection (AFCI), built-in surge protection devices (SPD), and weatherproof enclosures (e.g., IP65) suitable for outdoor mounting. Verify that required inverter safety features are present for your jurisdiction and that labeling matches your AHJ’s expectations. For backup sites, ensure transfer behavior and earthing schemes meet local rules when solar batteries are connected.
