Our portfolio of string inverters ensures efficient energy conversion, centralized maintenance, and scalable system design. Each model is carefully selected to meet the demands of modern solar installations while offering long-term durability and performance.

Overview of String Inverters

A string inverter is a critical component in photovoltaic (PV) systems. It connects multiple solar panels in a series (“string”) and converts the combined DC power into AC power for use or grid export. Compared to microinverters, string solar inverters offer simplified installation, lower cost per watt, and centralized maintenance.

Portlandia Electric Supply provides a wide range of single- and multi-string configurations to accommodate diverse system sizes, from small residential rooftops to large commercial solar farms. With robust design, high-quality components, and flexible configuration options, our string inverters are ideal for both new installations and system upgrades.

Grid-Tied Solutions with String Inverter Solar

Our string inverter solar devices are engineered for grid-tied solar systems. They synchronize the DC output from your panels with grid voltage, frequency, and phase, ensuring safe, reliable, and efficient energy delivery. Advanced models include Maximum Power Point Tracking (MPPT) to maximize energy harvest under variable sunlight conditions, optimizing system performance throughout the day.

These inverters are ideal for homeowners, commercial businesses, and developers who want a cost-effective, centralized solution without compromising on efficiency. With Portlandia Electric Supply, you get access to high-quality, industry-standard string inverter solar solutions backed by reliable support and technical guidance.

Hybrid String Inverter Solutions for Integrated Solar and Storage Systems

For projects requiring battery integration or enhanced energy independence, our hybrid string inverter solutions combine DC-to-AC conversion with intelligent battery management. These systems streamline installation by reducing component count and enable seamless switching between solar, battery, and grid power flows.

Hybrid string inverters are particularly useful for:

• Residential properties seeking energy backup during grid outages.
• Commercial solar systems requiring energy storage for peak load management.
• Developers implementing solar-plus-storage projects for sustainable energy efficiency
  
  

By integrating storage and solar conversion in a single device, hybrid string inverters simplify wiring, reduce system complexity, and provide a more reliable energy solution for both residential and commercial applications.

Frequently Asked Questions

What is a string inverter?
A string inverter connects multiple solar panels in series (“string”) and converts the aggregated DC power to AC for use or grid export.

How does a string inverter differ from microinverters?
Microinverters attach to individual panels, isolating performance per module. A string inverter centralizes conversion, simplifying installation and maintenance. Microinverters can mitigate shading effects but are costlier.

What is a hybrid string inverter?
A hybrid string inverter integrates DC-to-AC conversion with battery charge/discharge management, enabling solar + storage in a single device.

When should I choose a hybrid string inverter?
Choose a hybrid string inverter if you plan to incorporate battery storage or require backup power. It simplifies wiring, reduces system components, and ensures seamless operation.

Can string inverters operate under partial shading?
Performance may decrease if one or more panels are shaded, as the lowest-performing panel affects the entire string. Using power optimizers or module-level electronics can reduce the impact of shading.

Is it possible to expand a system with a string inverter?
Yes, if the inverter has spare input capacity or modular design. Planning capacity ahead simplifies future upgrades and ensures the system can accommodate additional panels.

What efficiency can I expect from string inverters?
Modern string inverters typically achieve 95–98% peak conversion efficiency under optimal conditions, ensuring minimal energy loss.

What is the typical lifespan of a string inverter?
Warranty and service life are generally 10–15 years. High-quality units, when properly maintained, can provide reliable operation well beyond this timeframe.

Are hybrid string inverters more expensive?
Yes, due to battery integration features. However, long-term returns from energy storage and system efficiency can justify the higher upfront investment.

How do I select the correct size string inverter?
Match the inverter’s DC input and maximum current/voltage ratings to your panel string configuration. Ensure sufficient capacity for expected output and allow flexibility for future system expansion.
