Solar Deep Cycle Battery FAQ

  1. Deep Cycle Batteries: What Are They?

    Deep cycle batteries resemble car batteries but operate very differently. Dissimilar to car batteries that ooze energy in short bursts, deep cycle batteries are equipped to provide power over longer duration. Though you can discharge deep cycle batteries up to 80 percent, yet manufacturers advise not discharging lower than 45 percent. You can shorten the life of your battery if you periodically go beyond the recommended limit.

  2. Solar Deep Cycle Batteries: How Do They Work?

    The energy that the solar panels absorb is stored in the solar batteries. If your battery has a higher capacity, then more solar energy can be stored. When using batteries during solar installation, you require an inverter, a charge controller, and solar panels.

    First, you have to connect the solar panels to the charge controller. By doing so, you can monitor the amount of energy that the battery is storing and avoid overcharging. Also, if the batteries deplete, the charge controllers will shut down the system. Plus, you have to connect the battery to the inverter for the conversion of the DC energy that the solar panels collect to AC energy for powering your appliances.

    If you’re using batteries as part of your home-based solar setup, then you’re able to store the excess electricity that the panels generate and not send the energy back to the grid. And only if your batteries are completely charged and the panels continue to produce energy, the electricity returns to the grid.

  3. Battery Storage: When Do We Need It?

    If you’re using a recreational van, battery storage is strongly recommended. Then, your gas-based generator is replaced by solar panels and batteries. And your appliances can continue to run even if the panels are not generating energy.

    In the case of homeowners who have access to an electrical grid, battery storage is useful but not a necessity. Even so, if you’re want to go off-grid or looking to keep the solar panels operational during grid outages, then consider the option of battery storage for uninterrupted energy.

  4. How Many Types of Deep Cycle Batteries Available?

    In deep cycle batteries, you have a range of options to take your lick from. For solar installations, the popular choices are sealed lead acid, flooded lead acid, and lithium-ion batteries. The flooded lead acid models are the cheapest options and can be availed at auto and big-box outlets.

    As compared to lead acid batteries, sealed lead acid batteries can store up to 15 percent more energy and get charged up to four times more quickly. Lithium-ion batteries are the costliest alternative, but they weigh lesser and can last up to four times longer than the lead-acid batteries.

Deep Cycle Solar Battery Buying Guide

As part of your shopping expeditions for batteries for your solar setup, you have to consider several aspects. These include voltage, capacity, price, and cycle life.

1. Capacity

Battery capacity determines the amount of energy that can be stored within. If you’re looking to power some appliances for long durations, go with more batteries, or greater battery capacity, for bearing the bulk load. The unit of measurement of capacity is total amp-hours.

2. Price

The prices of batteries can vary – ranging from approximately $100 for the lead acid battery to over $1500 for a lithium-ion battery. Also, you must take into account the lifetime costs and not only upfront expenses; lead acid batteries need to be replaced before the lithium-ion ones. More so, you need to incur more on maintenance for the flooded lead acid battery.

3. Cycle Life

The cycle life refers to the number of charge and discharge cycles of the battery before the capacity falls lower than the stipulated capacity. The capacity of different batteries tends to vary owing to the kind of technology that is used: the capacity of batteries is calculated in cycles.

4. Voltage

The voltage of the battery bank has to be compatible with the panels and the system as a whole – including the solar panels. In panels, you can avail the 12v and 24v models.

The 12v varieties are popular because many boats and RVs use 12v battery banks.

With a higher voltage battery bank, you can save money in the long run. Because you require lesser charge controllers and slender cables for the same amount of energy.

If your energy requirements are beyond 3KW, then the 48-volt systems are advisable. The large-sized off-grid home ones work on 48v.
