Microtex Solartech 12v solar battery for solar inverters

Can you use any 12 volt battery for solar?

No you can’t use any 12V battery for solar applications. Solar batteries require to be specially designed to recover from the obvious deep discharges it will get during those heavy rains & 3 or 4 sun-less days

12v 40Ah to 12v 200Ah

Microtex 12v flooded battery for Solar have excellent reserve capacity. Deep-cycle characteristics, and recover from deep discharges quickly.
12V Solar Flooded battery is robust in construction. Housed in modern high-impact Polypropylene copolymer (PPCP) hermetically heat sealed containers. We use woven gauntlets to eliminate shedding. Tubular plates ensure good capacity and long cycle life. 

Microtex Solartech batteries are built using very low antimony alloys, which makes sure that water loss is minimum. Water topping up intervals from 1& 1/2 years to 3 years is practically maintenance free! Making it the ideal choice for remote solar installations.

How long does a 12 volt solar battery last?

Typically a well designed solar battery should last over 5 to 6 years.

Used in solar UPS, Home solar inverter systems, solar street lighting and for solar off grid applications.

Which battery is best for solar system?

Flooded 12V lead-acid battery for solar power: Flooded battery offers the most economical solutions & the best return on investment when used as a 12V solar battery in home off-grid solutions & flooded solar batteries application. Flooded battery means the battery is vented & not sealed. A flooded battery requires to be topped up periodically. A well designed flooded battery will require water topping up only once in 18 months or more. Microtex batteries come with this feature as standard, thanks to specially designed alloys.

the best solar battery price 12v


What is the cost of small solar battery price?

Experience shows that 90% of batteries last only 4 to5 years.

Don’t let that happen! Choose long-lasting deep-cycle Solartech batteries from Microtex. Dependable lead acid battery capacity so you can get the complete performance of over 7 years. Your return on investment in Microtex batteries ensures the long term cost is way lower.

What is flooded battery life? How Microtex flooded battery performs?

Special designer lead alloys, with super additives, tin, low-antimony, arsenic, ensuring a really long life for your Microtex 12V flooded battery. In addition, we add nucleating agents like selenium,  sulfur & copper to ensure the lead electrodes do not corrode for a long time, ensuring a very long life. The addition of nucleating agents gives the grids a fine-grained structure with good corrosion resistance as otherwise, the coarse dendritic structure will be prone to hot cracking and porosity.
