Electrical system and fencing installation were begun again after lunch. Though the morning, Mr. Keng had been very busy on preparing battery connector alone with no one to help because most of us had to rush up solar panel installation to be completed following schedule. Until noon time, the panel installation was done and so Mr. Keng had several assistants. Berm, Thitjit and Sua helped him tightened bolt on battery shelf which was also by knock-down technique designed and produced by Mr. Aun. When all connectors were ready, Mr. Keng studied electrical circuit diagram provided by Mr. Pornlert. Then, he asked Tao and Aun to help applying metal C-Bar across interior wall to support plywood which Mr. Pornlert strongly emphasized several times to provide since before leaving Nakornprathom because it would be necessary to support all operating switches and system controller.
Mr. Thitjit sew the plank at measurement given by Aun and then took to apply on the supporting metal C-Bar while Mr. Pornlert unwrapped one of the most important engine which still in good condition after transportation. It was a new evolution of Bi-Directional inverter which was not only to invert AD current to AC current, but also able to load AC current to transfer out as well as an electricity supply system. Moreover, the inverter is able be a battery charger itself. As described, it was therefore not only to majoring perform as inverter of the solar cell system, also a generator might be connected directly whenever the solar cell current is insufficient or we need to increase load capacity of electricity supply.
It was Mr. Keng whose professionally well-prepared over 200 kilos of several full crates of accessories and equipments that everything would be available if anyone needs. Thus, in front of solar house stated several kinds of accessories spreading around. There, we had very enough equipment for everyone to fit kinds of work. As well as any other professional technicians, those kits are his personal beloved assets which he took over 10 years to collect, and will always be kept in good condition after work.
When Tao and Aun completely applied the plywood plank onto the back wall, the three kilos of inverter was then installed, following by controller, junction box, breaker box, battery bank breaker, electricity current meter, and AC current breaker.
All electrical equipment installation process was carefully done step by step following the diagram Mr. Pornlert had provided. The diagram also specified how to keep electricity main behind the plank for the reasons of security and tidiness, including how to place electricity main conduit securely. Mr. Keng paid attention on every single steps and details. He worked each step chronologically exactly following the diagram. And, without any rest, he continuously worked for several hours since the early morning until late at noon, only to rush up the process to be completed before the nightfall again, expectedly we might have electricity supply from the completed solar cell system at least for a time of our last night of the mission.
The procedure of battery connection began by inspect its current and condition by battery tester. After inspection, they would be separated orderly in groups; began with those contained more current. For this step, Mr. Pranuch whose just ran away from a bear during the morning patrol joined the connection while Mr. Berm, Pae, and Thitjit rearrange batteries in groups and then screwed releasing each sockets for connection. The batteries were separated into six strings; four for each. Then, they were connected, retaining at 48 volts. After that, battery main was linked to battery bank breaker before connected forward to inverter.
The problem was most of the battery WFCC previously delivered to Maharaja had not full-charged because lack of solar energy and that time only one panel available for charging. Moreover, as Mr. Pornlert informed, it would then take several weeks to re-charge all batteries in full capacity because it would be mostly clouded through the rainy season and we would have not enough solar energy to run the system in full operation itself. To help charging electricity current and to activate operational system of the Bi-Directional inverter, the generator which had just been relocated to standby nearby the solar house was then run, primarily in order to test the solar cell system operation.
By Mr. Keng (Thanabodi Urarak) experience and capability, all the process were finally completed in a very limited of time. Like Mr. Aun, Mr. Keng, on the other way, was admired by Mr. Pornlert on his electrical capability which again brought a great pride to all WFCC members.
At 5 pm, solar cell panel installation and all electrical system were completed, following by the fencing task of Mr. Jitti' s teamwork and signage installation done by Koh, Nut, Chai under control of Tao. And after the final task of painting by Mr. A was done, it was time of happiness and our tiresome was then vanished by pride. The solar cell system of Maharaja wildlife station was successfully completed following standard and under closely instruction and inspection of Mr. Pornlert. Now we; all participation, had driven Thungyai Naresuan WS to another step of effectiveness on wildlife protection and poacher suppression, also to support area management and wildlife research advancement in the future by the solar cell system; the unlimited permanent energy resources which is clean, save, cheap, and friendly to nature.
After kept all tools and materials, we went downhill to take a bath before joined dinner together at the station's canteen. That nigh, we were all glad with the first ice produced in Thungyai Naresuan WS by a refrigerator WFCC donated last month. During dinner, WFCC staffs and Thungyai's officers had a chance to exchange experiences and opinions with Mr. Pornlert and his followers among the breath of our beloved nature before separated to take a rest.
