2MVA Solar Step Up Pad Mount Transformer

Product Specification

2MVA Solar Step Up Pad Mount Transformer 380V to 34.5KV FR3 dielectric fluid Renewable Photovoltaic transformers

A solar transformer, also called a photovoltaic (PV) or PV step‑up transformer, is a key component in solar power systems. It enables efficient delivery of the electricity generated by solar panels: panels produce DC, inverters convert it to AC, and the transformer steps that AC up to the utility grid voltage so it can be properly connected, transmitted, and distributed.

3 phase pad mounted transformer is an easy-to-install distribution transformer with an anti-tamper and anti-theft design. It is widely used in photovoltaic projects in the North American market and is used to connect solar inverters to integrate electric energy into the grid.

WINLEY’s solar Step Up Pad Mount Transformer are designed for solar photovoltaic and energy storage medium-voltage applications. Friendlier to the environment, these pad-mounted transformers are filled with biodegradable and sustainable FR3 dielectric fluid, which also provides enhanced fire protection and a longer lifespan.

Key Benefits of Our Solar Step Up Pad Mount Transformer

• FR3 dielectric fluid: Uses FR3 fluid for improved fire safety and equipment reliability. Compared with mineral oil, FR3 significantly extends service life, making it ideal for BOS solutions in distributed energy resources (DER).
• Custom‑optimized design: Engineered to customer specs—loading profiles, impedance, and single- or multi‑inverter connections—so each unit delivers optimal performance for the site’s configuration.
• Higher overload capability: Designed to tolerate short‑term overloads beyond nameplate ratings without reducing insulation life, improving operational flexibility and uptime.
• Full BOS integration: Compatible with DC/AC combiners, disconnects, fuses, breakers, AC recombiners, pad‑mount switchgear, pole‑mount reclosers, air switches, capacitors, and associated services for seamless system deployment.
