Photovoltaic (pv) system is a typical fault need and the case of the processing

At the end of the year, your photovoltaic power station has been stable operation? Hair how much electricity in a year? Subsidies all received? （ The heart of three ask) ； Small solid as you plant consultant, remind everybody focus on plant health, such as found that the problem timely contact after-sales properly handle; Here small solid to 18 years in the fourth quarter of on-site service encounter power station malfunction made a summary to share with customers, hope on the installation and operations.

processing results: the scene found no grounding inverter side, the measured zero voltage is 5. 8 ~ 9. 0 v, the grounding row for processing in the distribution box, with zero voltage can be measured at 0. 001 v, the resumption of normal machine.

the small solid interpretation: in some weak power grid to power grid voltage transfinite need to adjust safety voltage range, safety check ac wiring without problems.

processing results: site trying to find a string of PV of abnormal voltage components, component side leakage, string for the group to do the wiring, the machine run normally.

earlier this year, the Clean Technica quoted a representative utilities Stratnet Norway's words: & other; Grid may be able to cope with, because even if the increase in the number of electric vehicles, power consumption will grow at a slower rate. Rely on electric power operation, even if all cars it will only add to Norway's electricity consumption by about 6%, if the intelligent charging, peak demand will rise only a few percentage points. On Thursday, in fact this situation is the worst, so please don't give you on Thursday night in the electric vehicle charging. ”

processing results: leak detection value to 300 bao ma, the rain, the normal operation of inverter, the inverter ground only inverter enclosure grounding four square aluminum wire received a stent, exchange did not grounding, grounding is not standard, let the customer to the ground.

processing results: communication junction box found at the scene of open jump again, found that open specification is too small ( 63) , and open and pick up the other load and the installer to replace open, remove access load.
