ZLLX-AC photovoltaic AC bus box is an important component that is suitable for photovoltaic series-connected power generation system. It receives series-connected inverter and AC power distribution cabinet or step-up transformer. The incoming line of the bus box adopts circuit breaker input, and the output adopts circuit breaker or load isolating switch. After bus convergence, secondary lightning protection is adopted. The rated voltage of the system is up to AC 690V. The protection level is IP65．at the same level as the series-connected inverter. It meets the requirements of outdoor installation and meets the requirements of waterproof, dustproof, ultraviolet protection, salt fog corrosion protection, etc. This product greatly simplifies the wiring between the series inverter and AC distribution cabinet or step-up transformer. The internal structure of this product is simple
and clear, and the wiring is neat and reasonable. High reliability and simple maintenance. Outdoor wall-mounted installation can adapt to various harsh environments. In addition to standard materials and sizes, it can be customized according to user requirements.
