View SpecificationsAs the economic epicenter of East Java (Jawa Timur) and Indonesia’s second-largest metropolitan hub, Surabaya is undergoing a monumental transition toward electrified mobility. Backed by Presidential Regulation (Perpres No. 55/2019) and strict state electric utility mandates (PLN SPKLU targets), Surabaya is rapidly building out high-density electric vehicle (EV) charging networks. With major industrial nodes such as the Rungkut Industrial Estate (SIER), Gresik Port Complex, and Tanjung Perak Logistics Corridor driving heavy commercial traffic, the demand for high-reliability, climate-hardened EV charging station installation services has reached an all-time high.
Key Takeaway for B2B Procurement Teams: Deploying charging infrastructure in Surabaya requires overcoming severe environmental and electrical constraints—specifically high coastal humidity, salt-spray oxidation, peak ambient temperatures exceeding 35°C, and PLN grid harmonic disturbances. Off-the-shelf equipment fails without marine-grade anti-corrosion treatments, intelligent dynamic load balancing (DLB), and battery-buffered power electronics.
International OEMs, real estate conglomerates, fleet operators, and municipal contractors in Surabaya require turnkey manufacturing and engineering support. As an established global manufacturer and exporter of commercial charging systems, energy storage cabinets, and precision enclosures, we deliver complete end-to-end solutions customized to the regulatory, thermal, and electrical landscape of Surabaya and greater East Java.

View Product SpecsExecuting an EV charging installation project in Surabaya requires strict alignment with Indonesian national regulations and localized utility parameters governed by PLN (Perusahaan Listrik Negara). Failure to adhere to local electrical code standardizations can lead to project delays, grid connection rejection, or premature component failure.
All hardware exported for Surabaya installation must comply with SNI 04-6292 (Electric Vehicle Charging Systems Safety) and international safety frameworks including IEC 61851-1 (Conductive Charging Systems) and IEC 62196 (Plugs, Sockets, Vehicle Connectors). Voltra Charger units undergo rigorous factory acceptance testing (FAT) to ensure total compliance prior to shipment.
For government and state-owned commercial tenders in East Java, meeting domestic content requirements (TKDN) is paramount. We support local Surabaya engineering contractors by supplying core power electronics, controllers, and modular sub-assemblies while enabling local fabrication of mounting structures, high-voltage transformers, and civil concrete pads.

Surabaya experiences high relative humidity (averaging 75%-90%) combined with elevated ambient temperatures and coastal air containing high salt levels from the Madura Strait. Standard charging equipment suffers from rapid PCB corrosion, moisture ingress, and thermal throttling. Our charging hardware utilizes IP65 sealed enclosures, conformal circuit board coatings, and C5-M anti-corrosion exterior powder paint specifically designed to resist tropical coastal environments.
Yes. Our chargers operate at 380V/400V 3-phase (50Hz), matching Indonesian electrical grid distribution parameters. Built-in Active Harmonic Filtering (AHF) keeps THD below 5%, satisfying strict PLN grid-tie requirements and avoiding utility penalty surcharges.
Our intelligent DLB system monitors total building power consumption in real time and dynamically adjusts the charging power allocated to each connected electric vehicle. If the building’s HVAC or machinery demands high power, charging speeds are automatically throttled down without tripping main circuit breakers.
Absolutely. All Voltra Charger units support standard OCPP 1.6J and OCPP 2.0.1 protocols. They connect seamlessly with any third-party Charging Station Management System (CSMS), enabling local QRIS payment integration, RFID user access, and dynamic tariff management in Surabaya.
Standard manufacturing lead times are 15 to 25 days depending on project order volume. Direct ocean freight from our plant to Tanjung Perak Port in Surabaya typically takes 7 to 12 days, ensuring rapid deployment for EPC site construction timelines.
