Parallel connection of solar panels and batteries with automatic ups system 12 volts installation.

Solar panels parallel connection and batteries with automatic ups system twelve volts installation is best because the current is accurate.

Most solar panels and batteries come in 12 volts, 24volts and 36 volts etc. If you want to add extra capacity to the system, you will have to wire the system in parallel configuration. Suppose a single battery powers up a ceiling fan for 6 hours. The same fan can be powered up for 12 almost double hours by two batteries having the same capacity connected in parallel. In addition, the two parallel connected solar panels will charge the batteries quickly and power up extra load.

This parallel wiring configuration is needed in case of 12 volts system such as 12 volts charge controller and inverter system. For this reason, two or more solar panels as well as batteries each of 12 volts direct current are connected in parallel.

Point to note is that we may also wire multiple solar panels and batteries in parallel for 12 volts, 24 volts, 36 volts or 48 volts direct current systems depending on our requirements.

We know that voltage in parallel connection is the same while current is different. Such currents are additive in parallel connection. In other words, the voltage level of both solar panels and batteries remains the same while current capacity Ampere hour in case of battery would add up increases. In simple words, two parallel connected solar panels or batteries each of 12 volts direct current, 120w, 10A would have.

10A + 10A = 20A.

Same is the case for batteries such as that we can increase the ampere hour capacity of batteries when connected in parallel.

100Ah + 100Ah = 200Ah

While the voltage of battery as well as solar panel remains same parallel connection.

V1 = V2 = V3 ..... Vn

Such 12 volts for both twelve volts solar panels and batteries.

Note that the amperes hour capacity of batteries as well as voltage level of solar panels must be the same for all batteries while connecting them in series or parallel.

The voltage level from both batteries and pv panels remains 12 volts while higher amperage capacity. We can connect the power generating pv panel and energy storage as backup in batteries with the 12 volts ups or inverter and solar charge controller.

The direct current to alternate current inverter is fed up by the direct solar panels during normal sunshine day and batteries in case of shading or night. The inverter inverts the 12 volts direct current to 120 volts alternate current which is United states of america volts or 230 volts alternate current which is volts for United kingdom and Europe depending on our local alternate current voltage levels and power up the alternate current loads such as light bulbs and fan etc. In addition, direct current operated devices can be directly connected to the charge controller direct current load terminals only.

To wire two or more solar panels and batteries in parallel, simply connect the positive terminal of solar panel or battery to the positive terminal of solar panel or battery and vise versa respectively.

The two 12 volts, 10A, 120w solar panels connected in parallel will charge the two 12 volts, 100Ah parallel connected batteries as well as power up the alternate current load through batteries and inverter during the day in normal sunshine. During shading or night when there is no generating power from solar panels, the battery stored energy will be used as a backup power and it will power up the alternate current load via inverter. This whole process is automatically done through ups such as it is hassle free and no manual action or changeover or automatic switch is needed to switch on or off electrical appliances and breakers.
