SHLX-PV4/1 DIY Solar Array Combiner Box with circuit breaker & electrical bus bar
● SHLX-PV2/1 combiner box is suitable for inverter (MAX input voltage DC550V/DC1000V,2 PV input channel, 1 output channel, single MPPT inverter). Box body is made of PVC engineering materials,with test for fire retardant, Temperature rise,anti impact, anti ultraviolet, and other testing. IP65 protection grade.
● Ingress protection of the combiner box reaches IP65, it is featured with waterproof, dustproof, rustproof, salt fog proof, can be used outdoors.
● Positive and negative poles of each PV string are equipped with special fuse wire, which protects the PV string from fault, use match-able fuse holder and fuse wire to reduce later maintenance cost for owner, and guarantee safety of maintenance personnel.
● It uses photo-voltaic purposed HV lightning protector to carry out protection to the positive pole-to-ground and negative pole-to-5.ground of bus after combination, the continuous operating voltage (Uc) reaches 1000VDC
● All external interfaces have lightning protection, Solar power generation system solar panel combiner box

Feature and application
1. Combines at most 24-channel DC input of PV strings into 1-channel output
2. Each channel is equipped with fuse wire, the output is equipped with lightning protector and circuit breaker
3. It greatly simplifies the input wiring of DC power distribution cabinet and inverter, provides lightning protection, short-circuit protection and ground protection.
4. Simultaneously access multipath solar power photovoltaic array, rated current of each line can reach 10A, IMax 15A, which can meet the requirements of different clients.
5. Equipped with DC fuse cutout in each input line to avoid system damage from over-current, make sure the system can operate steadily.
6. Equipped with DC high voltage lightning protection module in the output terminal, which can tolerate Max40kA lightning current.
7. Adopt high voltage breaker, the DC withstand voltage is not lower than DC1000V, safe and reliable.
8. With high power anti-reflaction device, which can avoid the countercurrent flowing backward due to the malfunction.
9. Protection level is IP65, which meets the using requirement of outdoor installation
