String Inverters

String inverters remain the workhorse of solar — one box converting DC from a string of panels to grid-ready AC, with the lowest cost per watt of any inverter architecture. This collection runs the full range: single-phase residential string inverters for home rooftops, and three-phase commercial machines from 25kW up to 275kW for carports, flat roofs, and ground mounts.

The commercial end is where this catalog goes deep. Solis three-phase inverters scale to 185kW and 255kW with 12 to 14 MPPTs and 5 to 10-year standard warranties — among the best cost-per-watt in the industry. Chint Power (CPS) 275kW 1500V inverters serve utility-scale and large C&I with 800Vac output. SMA's Sunny Highpower PEAK3 line — 125kVA to 180kVA at 480 to 690VAC — brings German engineering and SMA's legendary grid-support features to commercial builds. MidNite Solar rounds out the collection with balance-of-system and specialty conversion gear.

Single-phase buyers: match the inverter's MPPT count to your roof planes and its AC rating to your panel's DC-to-AC ratio (1.2 to 1.35 is typical). Commercial buyers: string sizing against 1000V or 1500V limits, rapid-shutdown compatibility, and monitoring platform all matter — our team configures commercial string systems daily. Send your array layout and we will spec the inverter, string map, and accessories.

Overview of String Inverters

A string inverter is a key component in photovoltaic (PV) systems. It links solar panels in series (“string”) and converts the DC power into usable AC power for homes or grid export. Compared to microinverters, string inverter solar models provide simpler installation, lower cost per watt, and easier centralized maintenance, which most installers prefer.

At Portlandia Electric Supply, we offer numerous single- and multi-string configurations that fit various system sizes. From small residential rooftops to large commercial solar farms, our string inverters feature robust design, reliable components, and flexible options. These products are suitable for new installations and performance upgrades.

Functions and Benefits of String Inverters

The main function of a solar inverter is to convert DC power from solar panels into AC power used in homes and businesses. String inverters connect multiple panels, optimizing system management through centralized inversion. This approach reduces installation complexity and maintenance efforts compared to module-level electronics.

Using string inverters also allows straightforward scalability of your solar system. They are designed for durability and consistent performance, incorporating technologies such as Maximum Power Point Tracking (MPPT). MPPT optimizes energy harvest by adjusting to sunlight variations throughout the day and seasons.

Grid-Tied Solutions with String Inverter Solar

Our string inverter solar devices are engineered specifically for grid-tied solar power systems. They synchronize the DC output from solar panels with grid voltage, frequency, and phase to ensure safe, efficient power delivery to your home or business.

Advanced models feature built-in MPPT technology. It maximizes energy capture during varying sunlight conditions. This ensures optimal system efficiency, delivering reliable output for long-term use. Our string inverter solar offerings support cost-effective, central solar energy conversion.

These inverters suit a variety of customers, including homeowners, commercial businesses, and developers. Portlandia Electric Supply complements these quality products with expert advice for system design and configuration.

Hybrid String Inverter Solutions for Solar and Storage Systems

For projects that include energy storage or need backup power, we provide dependable hybrid string inverter solutions. Hybrid string inverters combine DC-to-AC conversion with advanced battery charge and discharge management in a single device, streamlining the entire energy system.

These devices reduce installation complexity by minimizing the number of required components. They enable seamless switching between solar energy, battery reserves, and grid supply. As a result, hybrid string inverters enhance energy independence and offer reliable backup power.

Ideal use cases for hybrid string inverters include:

• Residential settings requiring energy backup during grid outages.
• Commercial solar systems managing peak loads with storage capabilities.
• Developers designing integrated solar-plus-storage projects to boost efficiency.

By integrating solar conversion and battery management, these hybrid products minimize wiring complexity. They provide dependable, all-in-one energy solutions for diverse applications.
