Features of HIITIO HS4 MLPE

HIITIO Flex MLPE (Module Level Power Electronics) is the perfect platform that lets you choose the equipment and features that maximize the benefit of your PV installations.

Power Optimization Increase Energy Output

HIITIO Optimizers get the most energy output from your PV array and minimize the losses from shading, module mismatch, degradation, and other issues.

Safe&Durable Enhance Safety and Compliance

HIITIO solutions meet US NEC Rapid Shutdown compliance and other countries required safety codes to protect O&M personnel safety

Monitoring lower Operating Cost

HIITIO could achieve panel-level performance monitoring and ensure precise problem-tracibility for EPCs and O&M personnel with its Energy Intelligence Platform, lowering O&M cost.

HS4 MLPE Platform

Increase energy output for mismatched modules up to 800W

Required：HCPT1 PV Transmitter
Module Level Rapid shutdown device for 1 solar module up to 800W

Required：HCPT1 PV Transmitter
Module Level Rapid shutdown device for 2 solar modules

Module-level monitoring for modules up to 800W

Enables UL PVRSS certified rapid shutdown with HS4-A-F and -2F units to meet required safety codes.

Solar Energy Optimization

Designed to mitigate mismatch power loss from shading, aging to complex PV layout like multi-orientations etc.

In addition to optimization, the HS3-A-O enables panel-level performance monitoring and rapid shutdown in compliance with NEC 2014, 2017, 2020.

HS3-A-O Smart Solar Power Optimizer

Features and Benefits

Suitable for up to 800W solar modules
One Module Per HS3-A-O
With selective deployment including the benefits of Safety & Monitoring
Anti-hot spot much safer
Mitigate 3%-25% Power Loss
More Durable: Weather resistant, IP68 rated and able to withstand harsh environment under -40℃-85℃
Long string installation available due to Voltage Limiting
With wireless 2.4GHz communications
25-year design life

PV Fire Safety

The HS4-A-F enables cost effective rapid shutdown functionality in a 1 module to 1 HS4 configuration. The HS4-A-F is both IEC and UL certified for global acceptance.

The HS4-A-F is UL 1741 PV Rapid Shutdown System (PVRSS) certified with hundreds of inverters to comply with NEC 2014, 2017, and 2020 rapid shutdown requirements. Many of the inverters with Sunspec communicate with the HS4-A-F over PLC, enabling plug and play installations.

HS4-A-F Photovoltaic Rapid Shutdown Switch

Features and Benefits

Up to 800W per channel
One module per HS4
IEC and UL certified
Meets US NEC690.12 rapid shutdown safety requirements
UL PVRSS certified with the largest network of inverters
16-80V, up to 25A (per channel)
MC4 (standard) connectors
Snaps to module frame for easy mounting
Does not require ground wire
PLC communication
25-year product life design and 12 years service warranty

HS4-A-2F Photovoltaic Rapid Shutdown Switch

Features and Benefits

The HS4-A-2F enables cost effective rapid shutdown functionality in a 1 module to 1 HS4 configuration. The HS4-A-F is both IEC and UL certified for global acceptance.

It is UL PVRSS certified for connectivity with the largest network of inverters, many of which have a built in RSS transmitter. By connecting to two modules, the TS4-A-2F reduces labor time and enables 16% fewer connections on a 14 panel string compared to single channel MLPE.

Up to 1600W (800W per channel)
Single MLPE connects to 2 PV modules
IEC and UL certified
Meets US NEC690.12 rapid shutdown safety requirements
UL PVRSS certified with the largest network of inverters
16-80V, up to 25A (per channel)
MC4 (standard) connectors
Snaps to module frame for easy mounting
Does not require ground wire
PLC communication
25-year product life design and 12 years service warranty

Module-level PV Monitoring

The HS4-A-M enables module-level monitoring sending alert notifications that are able to enable you to to proactively intervene early and maximize system uptime.

HS4-A-M Solar Communication Gateway

Features and Benefits

Enables module-level monitoring
View key performance information of each module
Lower O&M costs
Does not include rapid shutdown functionality
4G/WiFi wireless communication

PV TRANSMITTER HCPT1

Features and Benefits

When receiving the transmitted signal of the incoming controller, the component string channel is opened and the inverter operates normally;
When the transmit signal is not received, the MOSFET is quickly turned off, and the component string channel is also closed, so that the system’s high voltage is reduced to less than 30V within the 30s to ensure the safety of fire fighting and installation and maintenance personnel.

We now have professional automatic production lines and first-class testing and experimental equipment to provide quality assurance for the entire product, ensuring a daily production capacity of more than 100,000 sets.

Increase ROI of PV Projects with HIITIO HS4 MLPE

HIITIO HS4 series include a 25 years design life work perfectly to increase power (3.8%~25.7%) and optimize PV array performance so as to shorten the ROI period.

Simply Reliable with Fast, Easy Installations

10 Seconds Per Module
Each HS4 connects to the PV module at the junction box and clips to the module frame.

No Ground Wire Required
HS4 does not need a separate ground wire or mounting bolts for installations.

Water And Corrosion Resistant
HS4 are weather-resistant MLPE and also IP68 rated and able to withstand harsh environments under -40℃-85℃

Easier Operation & Maintenance with Module-Level Visibility

Based on wireless 2.4GHz communication and real-time monitoring of each individual panel, Hiitio optimizers could achieve panel-level performance insight and ensure precise problem-traceability for EPCs and O&M personnel on desktop monitoring platform and mobile monitoring app.
