When an inverter needs to be choosen, first, stick to the well known brands. It’s believeble an off-grid and hybrid inverter are attainable goal. This means it will be responsible for all energy consumption strategies and we need to choose the best solar inverter for our needs. When the need is raised to produce, process and store energy, solar inverter is the key.
Solar inverter will convert direct current (DC) output of photovoltaic (PV) solar panel into an alternating current (AC) which is used for several appliances. Inverter can also use the utility grid by taking grid power and use it for the appliances.
Choosing the right inverter
Back to Back distributes two off-grid solar inverters, i360 and Dopower. Off-Grid inverters are multitaskers. They combine inverters and chargers with bi-directional energy handling by converting DC to DC, DC to AC and AC to DC. This allows to the solar inverter to manage PV or other energy sources while also maintaining battery charge and loads demands.
It depends on how much it needs to run on solar, for example: if the total consumption is 10 kilowatt and you are willing, based on the space and budget, to convert only 30% of this to solar source, it should be choosen a solar inverter that only helps in getting the 30% out of total loads.
It’s advisable and recommended, when it is about inverter sizing, to add an extra power capacity +20%. Why? Because it is known that any equipment running all the time at full capacity, it does not give the best performance, niether the best life-time.
Finally, there are other types of inverters: string inverters, central inverters, micro invertersand, battery based inverters – but they are mainly used for commercial or the project basis purposes.
So, an off-grid home is now achieved, which means a start point in reducing power bills and start to not rely on municipal electrical power grid.
The quality of the solar inverter is important. A very low efficiency is a bad sign.
