My experience with Lithium batteries as a standby power system | Rare Techy
I wrote recently that the UN is dying to say that solar energy is a better source of power for Guyana than natural gas. Although some of my friends have questioned my decision, for Guyana natural gas and hydroelectricity are better for our development than solar energy. I also have reservations about the wind power here, but since I don’t have much information on the matter, I won’t go into that area.
But here are my recommendations for solar energy that I was able to make as the Vice Chairman of the Guyana Sugar Corporation. “The installation of solar power at the GuySuCo Headquarters is a project that has been fully funded by the government, through the Guyana Energy Agency. A 133 kW (peak) grid tie installation was installed at a cost of G$41,347,149. The system has no energy storage, such as batteries that cost nearly three times as much as G$120 million, so energy must be consumed immediately when it occurs. Therefore, when the generated power exceeds the amount required by the connected load, the excess power is fed into the grid. Likewise, if the electricity produced is less than the power required by the load, the event will be drawn from the grid.”
“The size of the building is based on the electrical assessment of the Headquarters building when it was located in LBI.
Since the move to LBI, the need for the Headquarters building has been reduced to less than 50% of the previous assessment, largely due to the replacement of outdated air conditioners with high efficiency inverter units. well, and use candles. Therefore, less than 50% of the energy consumed in the solar area. Based on this, and since GPL does not provide payment for the electricity installed in the grid, it was decided to feed the electricity to the MMD and ISD facility from the solar power plant as well. The combined energy of the three buildings is 24,500 kWh per month, and the electricity generated by the solar system is 12,000 kWh per month.
The above information is based on input using estimates and little else. The daily generation from 2020 to now is estimated to be 40% of installed capacity, although no solar system is 100 percent efficient, they hoped [given our 100 inches of rainfall per year and overcast skies I have alluded to] about 60% as good as possible, no! Much less, it points to the fact that having solar power as the first and most reliable and economical system in Guyana is unlikely to happen.
However, due to our heavy black record to date, I have installed a battery backup system in my home. Built on 4 large Lithium Ion batteries [200 amps @48 volts] and the inverter takes the GPL power and acts as an uninterruptible power system. When the black comes on it slowly switches to the battery and runs your house for a few hours when the GPL power comes back on then back to GPL and the battery charges until the next black comes on. No more fumbling around in the dark, out in the rain when the sizzle starts, or gasoline standing next to the builders, I hope no one is in their house, don’t go to the gas station every time to buy gas or diesel. motor oil, there is no storage of these highly flammable chemicals on your house, everything in the house includes batteries and a switch, so no safety is required to operate it.
As in the past there are no regulations regarding the noise or location of these generators, your neighbor can, and often does, blow his pipe into your house without warning. just be careful. Anyway, I was surprised at how well this thing worked and I’m very happy to keep the little machine I use with all the problems.
I haven’t bought solar panels yet, as this is a standalone system at this point. And it’s so convenient, so noisy and automatic, so much, I don’t know that black is dying. At least we are benefiting in this way from the advances in solar technology. And the most surprising thing is that it costs much less than installing a physical machine since all the equipment is sold and free.
