Parts & compatibility

Start with the exact product before choosing a component.

Use model numbers, voltage/current limits, connectors, communications and manufacturer documentation to narrow compatible parts. Use the documented compatibility evidence shown with a part before buying it for a specific system.

Compatibility first

Model number, voltage/current, connector, firmware and communications matter more than appearance.

Compatibility by component family

Start with the component family, then verify the exact product pairing.

Use each family as a route into model-specific compatibility evidence. Empty or uncertain pairings are not padded with unrelated products.

Compatibility options

Monitoring & communications

Meters, CTs, shunts, gateways, dongles, CAN and RS485 equipment.

Search parts & controls

Search by part, brand or component type.

Filter by brand and type, then check the compatibility basis on each result before buying. If evidence is missing, Melnti does not substitute an unrelated product.

Local help

Need a component installed, sourced or checked near you?

Search the installer directory by city or town. Melnti shows direct service-area evidence first, then wider regional/country options without presenting them as locally based.

Compatibility labels

“Looks compatible” is not a compatibility standard.

  • OEM / original when the manufacturer documents the part
  • Manufacturer-approved when an official compatibility source exists
  • Documented compatible when reliable technical documentation supports the pairing
  • Universal only for genuinely standardized components within their ratings

Find the component, not just the category

Solar systems depend on more than panels, batteries and inverters. Melnti groups source-backed expansion batteries, charge controllers, optimizers, microinverters, monitoring hardware, meters, communications equipment, backup accessories and related components so people can search by brand and equipment family.

Compatibility comes before appearance

Two connectors or accessories can look similar and still be electrically or digitally incompatible. Melnti treats OEM, manufacturer-approved, documented-compatible and generic/universal components as different evidence levels. Confirm model numbers, voltage/current limits, communications, firmware and regional documentation before installation.
