Core products

Satellite Communication Energy Cabinet
Satellite Communication Energy Cabinet

The Satellite Communication Energy Cabinet is a PV energy storage cabinet from Highjoule Technology Group designed specifically for off-grid satellite communication sites. The system consists of PV modules, an MPPT solar controller, an LFP (Lithium Iron Phosphate) battery pack, a thermal management system, and a power distribution unit, forming a complete off-grid PV generation and energy storage system that provides stable power to satellite communication base stations. The system adopts a modular design and can be efficiently operated and maintained via local and remote monitoring. It supplies 48V DC and AC 120V–200V power to satellite and other industry communication equipment, supporting floor-standing and pole-mount installation.

Outdoor Battery Cabinet
Outdoor Battery Cabinet

The Outdoor Battery product line is centered on green low-carbon, high-efficiency, and intelligent coordination principles. It covers both indoor and outdoor configurations, with lithium batteries (or lead-acid batteries) forming battery energy storage cabinets. Each cabinet also houses environmental sensors, battery circuit breakers, battery cables, and thermal management accessories to form an integrated battery cabinet.

Hybrid Power System
Hybrid Power System

The Site Hybrid Power System is a next-generation multi-energy integrated power supply for 4G/5G base stations, communication equipment rooms, edge data centers, and outdoor compact sites. It breaks the traditional “single grid input, single DC output” architecture to achieve multi-source energy input + multi-voltage output + intelligent coordinated dispatch. At the site level, it accommodates grid power, PV, energy storage, diesel generators, and other sources, delivering a highly reliable, efficient, and simply deployable power framework for 5G equipment, transmission equipment, and IoT loads. Power range: 6 kW–36 kW; available in both 3U and 1U circuit breaker configurations.

Stacked-PV MPPT Solar Controller
Stacked-PV MPPT Solar Controller

The Stacked-PV MPPT Solar Controller is specially developed for PV capacity expansion at base station sites. Using a series-connection scheme, the system consists of PV modules, a stacked-PV MPPT controller, and a DC meter. Each PV string is series-connected to the controller, which steps down the module output voltage to −48V and injects it onto the rectifier output busbar to supply DC loads. Designed for communication base stations, it supports wall-mount and pole-mount installation. The product is available in outdoor and rack-mount versions.

Outdoor Hybrid Energy Cabinet
