String, micro, hybrid and legacy
String versus micro versus hybrid, by project type
Decision frameworks compare string inverters, microinverters and hybrid units by system size, shading profile and storage plans, not brand preference. Use it to avoid over-speccing a small job with commercial-grade equipment, or under-speccing a shaded roof with a single string inverter.
Legacy replacement cross-references
Retiring or hard-to-source units from SMA, Fronius, ABB and other legacy brands map to current, in-production equivalents by voltage window, power rating and communication protocol. That mapping keeps a repowering job from stalling on a part number nobody stocks anymore.
Hybrid and storage-ready selection
Not every inverter marketed as storage-ready supports both AC and DC-coupled battery configurations, and the difference changes system cost and round-trip efficiency. This guide flags which listed units support which coupling method before it becomes a change order.
Specify, standardize and plan repowering
Specify with confidence
Inverter class matches to project type and storage plans up front, so the spec doesn't change mid-project.
Standardize the install crew's toolkit
Fewer inverter brands and firmware quirks across a portfolio means less time on hold with technical support and fewer truck rolls for commissioning issues.
Plan repowering before failures force it
Legacy cross-reference data lets an aging fleet get a replacement plan before a warranty expires or a manufacturer exits the market.
Inverters set string sizing math
Inverters set the string sizing math
Module open-circuit voltage and temperature coefficients determine maximum string length under NEC 690.7, and battery chemistry determines which hybrid units are compatible. Cross-check the panel and battery guides before finalizing string design.
FAQs
Should I use a string inverter or microinverters?
It depends on the project. Microinverters suit roofs with shading or multiple orientations and give module-level monitoring, while string inverters are usually more cost-effective on larger, uniform arrays with a clean single plane. Weigh shading, roof complexity, and budget against the array size. Sunhub lets you compare string, micro, and hybrid options by project economics so the choice lines up with the actual job.
What inverters support both AC and DC-coupled batteries?
Hybrid, or storage-ready, inverters are the ones built to work with batteries, and many support DC coupling directly while also allowing AC-coupled storage. Exact compatibility varies by model and battery chemistry, so verify the pairing on the manufacturer's spec sheet before you commit. Sunhub's hybrid and storage-ready listings help you filter to inverters that fit the battery approach you are planning.
How do I find a replacement for a discontinued inverter?
Match the failed unit's key parameters, power rating, voltage window, MPPT count, and string configuration, then find a current model that meets or exceeds them and fits the existing wiring. Sunhub maintains cross-references for retiring and legacy brands, so you can move from a discontinued model to a supported equivalent without re-deriving the string sizing math from scratch.
