Guys,


meron akong 400 watt / 220 AC na water pump pwede na kay a itong i-plug sa 1000 watt pure sine wave inverter?


 Thanks,
I love the smell of napalm in the morning!

successfully harvest underground water using 12v water pump 180-watt.  planning to connect it to my 200-watt solar farm.

Nasira na yung battery (no longer holds a charge) ko about a year ago. Thinking about refurbishing it when other projects get done.

pag brownout walang power din yung  solar namin kasi wala naman naka standby na battery.although meron kaming naka standby na generator (65KVA).

mahal kasi ang battery at me life span ,hinde  siya worth it maginstall mahirap ang ROI(return of investment)

ah ang akala ko sa solar setup laging may battery to store the harvested power from the sun? tapos battery > inverter > output

so yung setup ng sa inyo solar panel > converter/ inverter??? > output direct sa mga gamit?
ilang KW ang kayang iload ng direct sa panel?

In some setups the battery acts as a regulator (like a UPS) to keep the voltages constant for the AC converter. I guess may parang capacitor yung setup niya.

yung malaki na inverter is 5kw(white and yellow) and yung blue inverter 1.5 kw a total of 28 kilowatts.

so you mean to say to PANELS directly supply Elctricity (220V AC)?
how many panels & what laods can be used? Aircon is OK?
yan ba yung On Grid or Off Grid na setup?

you need the inverter to supply 220 volts AC each inverter(white and yellow) is 5 kilowatts
each solar  panel may reproduce 312.5 watts
load is ,as long as AC power single phase
grid on

What is the difference between On-grid and off-grid solar power? On-grid means your solar system is tied to your local utilityís GRID. This is what most residential homes will use because you are covered if your solar system under or over-produces in regard to your varying energy needs. All this means for you is that your utility system acts as your battery space. If you are producing more energy with your solar panels or system than you are using, the excess energy is sent to your gridís power company, allowing you to build credit that you can cash out with at the end of the year, in a process called net metering. Being grid-tied is beneficial because you  donít  have  to  buy  an  expensive  battery  back-up system  to  store  any  excess energy. Being off-grid means you are not connected in any way to your gridís power system or  utility  company.  This  is  appealing  because  you  are  100%  self-sustaining  your energy use. However, there are disadvantages because off-grid systems require you to  purchase  back-up  battery  which  can  be  expensive,  bulky,  and  not  very environmentally friendly which defeats the purpose of going solar (save money and live greener).

They call on grid setup as "Grid Tie Systems"...
These systems are connected directly/parallel to Meralco's service line. When the panels are producing electricity, the feed from Meralco whittles down. If the panels can supply all your electrical needs, the service line feed is totally cut off.

Does your Meralco meter run backwards when you have a surplus of solar power? How hard is it to apply for net metering? My boss has a solar setup at home and he mentions something about having to pay taxes or something if you apply for net metering.

no more switching is done, automatic na siya kapag  daytime sa solar siya kumukuha ng power and meralco power is switch is off,kapag night time naman sa meralco siya kukuha ng power

In word: HARD

One of our offices has an off-grid setup. But the procedure for net-metering is so convoluted we gave up and simply use the setup during power outages in lieu of gas generators.
