Hybrid solar systems are use batteries to store energy for later use. A hybrid Solar system generated from the photovoltaic system combines with another power generating energy source. It also operates as a backup power supply during a blackout, almost like a UPS (Uninterrupted Power Supply).
Technically, the hybrid solar system refers to two-generation such as solar and wind. However, the term “hybrid solar system” refers to battery storage and solar. Hybrid solar systems are the simplest you get the guaranteed (well, 99.9% of the time) electricity supply of the grid, with the power to store your excess solar power to be used when the sun isn’t shining. A hybrid solar system reduces your dependence on grid imports by 70% to 95%.
Hybrid systems don’t require diesel backup. They’re still costlier than a purely on-grid system, though – typically double the worth of grid-connect solar.
Equipment for Hybrid Solar Systems
Hybrid solar systems are based on the following components:
- Charge Controller
- Battery Bank
- Battery-Based Grid-Tie Inverter
- Power Meter
- DC Disconnect (additional)
How Hybrid Solar System Works?
A hybrid system uses PV power during day time which accesses to save power in batteries for later use. The main design considerations are your peak power usage i.e. the foremost power you’ll use at any point in time and therefore the amount of power in kWh that you simply expect to use during non-solar producing hours. From point of contact, Eco electric will help guide you towards the right sort of system by completing an in-depth design and estimation process.
If the weather is not suitable and there is power breakout for a long-time hybrid solar system switches to main power when it requires ensuring consistent power and there is no damage to the battery.
Types of Hybrid Solar System:
Hybrid solar systems have four main categories:
- Basic hybrid inverters (no backup power)
- All-in-one battery energy storage systems (BESS)
- Advanced AC-coupled systems (off-grid or hybrid)
- Multi-mode hybrid inverter (with backup power)
Basic Hybrid Inverters (no backup power):
This is a basic type of hybrid solar inverter but also enables storage of solar power in battery systems for self-use. The most disadvantage of this sort of Inverter is that’s doesn’t contain a grid isolation device which suggests it cannot supply power when there’s a blackout. If grid stability isn’t a problem then this easy hybrid inverter would be a good economical choice.
All-in-One Battery Energy Storage Systems (BESS):
A newer trend is to package hybrid inverters along with a battery system in one complete unit is often technically this is referred to as a BESS (Battery Energy Storage System) which may be retrofitted to a home with an existing system. These systems are available during a sort of size and are usually about the dimensions of a medium fridge.
There are two types of BESS systems. The common (AC coupled) battery systems like the Tesla Powerwall 2 and Sonnen ECO, and therefore the all-in-one BESS systems which include a solar inverter (DC coupled).
Advanced AC-Coupled Systems (Off-Grid or hybrid):
Most hybrid systems consisted of two different inverters that worked together to make what’s referred to as an AC coupled system; a typical solar inverter and a classy interactive or multi-mode battery inverter.
The Solar inverter is often any standard unit but it’s usually either an equivalent brand or is compatible with the interactive inverter to optimize battery charging.
The interactive or multi-mode inverter acts as a battery inverter/charger and complete energy management system, using clever programmable software to optimize energy usage. Interactive inverters supply power also to the grid connection (import and export power) and may be set up to automatically start and run a back-up gen-set (generator).
Multi-mode Hybrid Inverter (with backup power):
Multi-mode hybrid inverter (with backup power) is the most advanced hybrid inverter. It also has a power back capability, it can supply power to the home and charge batteries under normal operation.
If there is a complete blackout in the grid it automatically switches to battery start in 3 to 5 seconds and provides power to a full house.
Benefits of Hybrid Solar Systems:
Continuous Power Supply
The hybrid solar systems provide power continuously, with no interruption, because the batteries connected to the store the energy. So, when there’s an electricity outage, the batteries work as an inverter to supply your backup. This is often also the case during the evening or already dark when there’s no sun and energy isn’t being generated; batteries provide the back-up and life goes on with no interruption.
Utilize the Renewable Sources in the Best Way
The battery is automatically connected to the system to store the energy, there’s no waste of the energy generated on bright sunny days. So, these systems make use of renewable energy in the best way, storing energy on an honest day and utilize the stored power on a nasty day, the balance is maintained.
Low Maintenance Cost
The upkeep cost of the hybrid solar power systems is low as compared to the normal generators which use diesel as fuel. No fuel is employed and that they don’t require frequent servicing.
Hybrid solar power systems work more efficiently than generators which waste fuel under certain conditions. Hybrid solar systems work efficiently altogether sorts of conditions without wasting fuel.
Unlike traditional generators, which give high power as soon as they are turned on, most hybrid solar energy systems manage load accordingly. A hybrid system may have technology that adjusts the energy supply consistent with the devices they’re connected to, whether it’s an air conditioning requiring high power or a lover that needs less.
The hybrid solar system is best for your homes its benefits clear that it is suitable for a home in every way because of its lower cost, high efficiency, and much more!
