If you opt for off grid solar inverters rather than grid-tie system, then make use of batteries in order to store all the energy your solar power system generates. The type of battery that is required to be used is called
solar inverter deep cycle battery, that has the capacity to handle repeated discharges and recharged over many years of service. The most commonly used deep cycle batteries are acid, lead, gel, and absorbed glass matte (AGM).
Solar panel technology is changing so rapidly that your current solar panels may not be available when you want to upgrade. Your inverter may not be able to accommodate the mismatch of solar panels, which may mean you'll need to buy a new one. A way to overcome this potential problem is to perhaps consider a multi-string or a MMPT expandable solar inverter (see below).
Popularly there are a number of types and varieties of solar power inverters to choose from depending on the amount of power that you want. You have the option to choose from like single phase solar inverter, three-phase solar inverter, parallels solar inverter or else can go with the series solar inverter models. So before buying any inverter you need to determine which one is going well with your needs.
A battery ready system uses a hybrid inverter rather than a typical string solar inverter Most modern hybrid inverters have the battery charger and connection built in which makes adding a battery much easier in the future. However hybrid inverters are more expensive and if you don't add batteries during the installation finding compatible batteries after a few years could become difficult.
Solar inverter also know as solar power inverter or solar energy inverter and this the heart of solar power It is an equipment that converts solar panel's DC (direct current) power into AC (alternating current) power. This intelligent solar inverter also matches the required frequency, volt etc with electrical grid to run our load to be used at household and commercial premises.
It is possible to use solar energy without battery. You can use an on grid or grid tied system. The solar panel will absorb the sunlight, then the solar inverter will handle the DC to AC conversion. If there is any excess production, it will be exported to the grid network according to local regulation. It's worth noting that this system will not be operational during the night nor during blackouts.
I recently converted my inverter to a solar inverter, which made the whole thing less expensive. It cost me about Rs. 15000. Urja Solutions in Bangalore fixed a couple of solar panels on the roof and connected these to the inverter. It's fantastic to have free power for my lights, fans, television and computers during the day. I'm told I'll cut my power bills by half. Time will tell.
