Compared with ordinary universal photovoltaic cables and non-matching connecting wires on the market, the Growatt 4P male straight direct-connected PV-energy storage cable has exclusive matching advantages, superior performance and higher safety, fully adapting to the personalized operation needs of Growatt supporting energy storage systems.

Exclusive Growatt Original Matching, Zero Compatibility Risk

This cable is specially developed and produced for Growatt energy storage inverters and battery systems. The 4P male straight tube-end connector adopts customized size and pin definition, which is completely consistent with the interface protocol of Growatt WIT, SPH, AXE and other series of energy storage equipment. It realizes one-step direct plug-in connection without any adapter, conversion line or wiring modification. It completely avoids hidden dangers such as poor contact, signal interruption and equipment failure caused by interface mismatch and protocol incompatibility of ordinary cables, ensuring 99% stable docking of power and signal transmission, and greatly improving the overall operation stability of the energy storage system.

Ultra-low Loss Power Transmission, High Energy Efficiency & Power Saving

Adopting high-purity tinned copper stranded conductor, the cable has extremely low internal resistance and excellent electrical conductivity. Compared with ordinary aluminum-clad copper and low-purity copper cables, its power transmission loss is reduced by more than 40%. In the long-term charging and discharging cycle of photovoltaic energy storage systems, it can effectively reduce electric energy loss, improve the overall power generation and grid-connected efficiency of the system, and create higher economic benefits for users. The optimized conductor structure makes the cable generate little heat during high-load operation, avoiding performance attenuation and aging acceleration caused by overheating, and maintaining efficient and stable power transmission all the year round.

Extreme Environmental Resistance & Long Service Life

Flame-retardant and anti-aging sheath can resist ultraviolet radiation, high-temperature oxidation, low-temperature embrittlement, rainwater corrosion and chemical erosion. Whether it is high-temperature and dry desert areas, humid and rainy coastal areas, or cold northern regions, the cable can maintain intact structural performance and stable electrical indexes. The IP65 full-sealed waterproof and dustproof design of the connector prevents water vapor and dust from entering the connection gap, avoiding oxidation and rust of the contact pin, poor contact and line failure. After professional long-term aging test and mechanical fatigue test, the product can withstand frequent plugging and unplugging and long-term bending laying, with a service life of up to 25 years, which is synchronized with the service life of photovoltaic power stations, greatly reducing later maintenance and replacement costs.

High Safety & Simple Installation Operation

The product has multiple safety protection performances such as flame retardant, fire prevention, waterproof, dustproof, anti-creepage and anti-short circuit. It will not produce toxic smoke and harmful gas when encountering high temperature and open fire, which reduces the risk of fire spread in photovoltaic systems. The integrated molding process of the connector and cable avoids the risk of wire falling off and virtual connection caused by traditional crimping wiring. The straight tube-end plug-in design is simple and fast to install, supports on-site quick wiring, does not require professional welding and crimping tools, greatly shortens the construction cycle of photovoltaic energy storage projects and reduces on-site construction costs.
