    1. Mercury 1.6kva is 24v inverter. Your battery has to be connected in series to make 24v inverter. Then your loads determines your backup time.

  2. How much is 10kva AVR and 5000VA inverter, how many 200AH batteries and solar panels does it required and their cost also

    1. Good day Sir, Mercury 10kva AVR Single phase is #128,400.
      Also, Mercury 5kva Complete Inverter System 4x 200ah deep cycle,8x 300 watts Mono Solar Panel is #1,667,460

  3. Please i need this information.
    What would i need as regard AVR, inverter, baterries and solar panels to power a 3 bedroom apartment containing 4 1HP split ACs, i deep freezer, a giant refrigerator, 2 led 42in TV sets, 5 ceiling fans and energy bulbs both inside and outside. What does this amount to in terms of quotation.

  4. Pls send quote for the following
    1. 3.5 kva sine wave inverter
    2. 200mah deep cycle batteries x4
    3. MPPT Charge controller
    4. 250W Solar panels x8
    5. Automatic voltage regulator
    Please how long is the warranty and how long does it take to ship out after confirming payment order and when does it get to me after shipping.
    Where are you shipping from.
    I live in Zaria

  5. The Mercury modified sine wave inverter with charger(2.4kva) I used with two 100ah battery, the inverter is not charging the battery.

  6. What size of inverter do you recommend for a house with 79 internal low energy bulbs and 70 external low energy bulbs, 6 nos Gen cool airconditioners, 3 nos regular airconditioners, 1 deep freezer, 3 refrigerator, 1 borehole pump, 1 swimming pool pump, 1 booster pump.
    All of this are not on at the same time

  7. How do I install the 5000 AVR to the 2400VA inverter…. I have been having low voltage of about 120V in my area now.

    I need your quick reply on this.

    1. the stabilizer output will go to the wall socket then the inverter will be connected to the back of the stabilizer

  8. There is a continuous sound when my modified 2kva mercury inverter
