Explore our factory-direct smart AC wallboxes, high-power DC fast charging systems, and modular battery energy storage solutions built to international grid specifications.
As mass-market electric vehicle adoption surges, the residential sector has transitioned from passive overnight trickle charging to active, bi-directional nodes within distributed energy resource (DER) ecosystems. Level 2 AC home chargers (ranging from 7.4 kW single-phase to 22 kW three-phase) represent over 80% of all EV energy dispensation globally, placing unprecedented localized stress on municipal low-voltage distribution transformers.
Local current transformers (CT clamps) or direct Modbus/RS485 energy meters continuously sample instantaneous whole-home consumption. The OEM Level 2 charger adjusts its PWM pilot signal or ISO 15118 duty cycle in sub-second increments, preventing main circuit breaker trips without requiring expensive service panel upgrades.
Modern residential EVSE functions as an adaptive sink for intermittent photovoltaic generation. Through seamless API handshake with hybrid inverters and stationary lithium iron phosphate (LFP) storage, chargers track real-time excess solar curve generation, locking charging current precisely to local surplus.
The transition toward ISO 15118-20 and SAE J3400 (NACS) enables off-board residential DC wallboxes and bi-directional AC on-board charger synchronization. OEM Level 2 chargers are now evolving into dual-inversion interfaces capable of powering home microgrids during blackouts or utility peak pricing.
Supplying OEM Level 2 chargers internationally requires navigating distinct electrical wiring topologies, protective relay mandates, and national cybersecurity statutes. A unified OEM architecture must reconcile split-phase (120/240V) North American grids with three-phase (230/400V) European and APAC electrical standards.

HizonSun's OEM mainboards integrate high-frequency fluxgate magnetic sensors capable of detecting both 30mA AC earth leakages and 6mA smooth DC residual currents. This negates the requirement for costly Type B upstream RCD installations in European domestic switchboards, saving end-users over €250 per installation.
For the UK and Commonwealth regions operating TN-C-S PME earthing arrangements, our hardware incorporates open-PEN conductor fault monitoring. The relay isolates all live phases and neutral within 4 seconds of voltage fluctuating beyond 207V–253V, entirely avoiding the need for dedicated earth electrodes.
Meeting the UK PSTI Act and California SB-327 mandates, every OEM residential motherboard is equipped with an automotive-grade secure element (SE/TPM). Cryptographic private keys for TLS 1.3 encryption, Wi-Fi WPA3 enterprise authentication, and Over-the-Air (OTA) firmware integrity verification remain tamper-proof.
Operating from our dedicated smart manufacturing facility in Kunshan, Jiangsu Province, Suzhou HizonSun Tech Co., Ltd. controls the complete production chain. By decoupling design from third-party assemblers, we offer tier-one automotive manufacturers, utilities, and charging network brands an unmatched level of OEM customization and quality assurance.
Our multi-tier Surface Mount Technology (SMT) lines feature 3D Solder Paste Inspection (SPI) and automated optical inspection (AOI) ensuring micron-level solder integrity. Sensitive power measurement and microcontroller circuits undergo automated dual-layer robotic polyurethane conformal coating to prevent moisture, dust, and corrosive salt-fog degradation.
Every single OEM Level 2 wallbox assembly passes through our automated regenerative burn-in chamber. Units are stressed at 100% continuous rated current (up to 48A / 80A single phase or 32A three-phase) under 50°C ambient temperatures for 4 to 8 hours with continuous oscilloscope monitoring of thermal drift and switching noise.
We deliver complete mechanical and firmware re-branding within 4 to 6 weeks. Options encompass injection molded outer enclosures (fire retardant UL 94 V-0 polycarbonate), front glass panel screen printing, custom 4.3" or 7" HMI graphical user interfaces, bespoke mobile apps (iOS & Android), and dedicated OCPP cloud endpoints.
Residential EVSE must operate flawlessly in environments ranging from sub-zero Scandinavian and Canadian winters to the hyper-arid, high-ambient heat of the Middle East and Australia.
Condominium parking environments feature constrained main breaker thresholds. Our master-slave local mesh hierarchy allows up to 32 chargers to communicate via local 2.4GHz Wi-Fi or RS-485 bus without reliance on public cloud up-links, dynamically sharing available building headroom while allocating individual tenant billing through RFID / NFC cards.
Equipped with low-temperature silicone charging cables that retain elasticity down to -40°C, internal PCB heating trace resistors, and condensation-preventing hydrophobic gore vents. Electronic relays feature cold-welding prevention logic ensuring solid pilot pin contact even when caked with frozen slush.
Engineered with double-walled thermal deflection casing, UV-stabilized anti-yellowing PC-ABS plastics, and non-ventilated IP65 sealed compartments. Rated to deliver continuous 11 kW output at 55°C without thermal current derating, tested against severe blowing desert sand and tropical monsoons.
The distinction between residential AC charging and entry-level DC fast charging is dissolving. Our Kunshan R&D centre is advancing three transformative technological paradigms for delivery in 2026–2028.
Eliminating RFID cards and smart phone apps entirely. By executing public key cryptography (PKI) directly over the control pilot (PLC HomePlug GreenPHY), vehicle verification and automated billing occur within 1.2 seconds of physical nozzle insertion, supporting automatic bi-directional discharge parameters.
Bypassing the car's constrained On-Board Charger (OBC) via compact DC architecture. Utilizing 1200V Silicon Carbide MOSFET power modules operating at >100kHz switching frequencies, these residential units deliver ultra-dense 20kW–30kW fast top-ups with >96.5% electrical efficiency in a compact wallbox form factor.
Moving beyond isolated Wi-Fi setups that depend on proprietary cloud servers. Embedding low-power Thread mesh radios running the unified Matter application layer allows OEM chargers to natively synchronize with Apple HomeKit, Google Home, Amazon Alexa, and home solar storage arrays without vendor lock-in.
