Frequently Asked Questions
The short answer is yes. The longer answer is that better, more efficient sensitizers for solar panels may be what finally propels solar power into the mainstream. A sensitizer is a dye that increases the sensitivity of a semiconductor (a component that conducts a little amount of electricity) to sunlight. The more energy a panel can get from the same amount of light, the better the sensitizer. Although scientists have been working with sensitizers for many years, current findings indicate greater promise.
Short Answer: The size you choose depends on the watts (or amps) of what you want to run (find the power consumption by referring to the specification plate on the appliance or tool). We recommend you buy a larger model than you think you’ll need (at least 10% to 20% more than your largest load). Read more
If you have an inverter/charger, then it will likely incorporate an automatic transfer switch. This ensures that outside AC power is used when it is available. It will also switch the inverter from inverting mode to charging mode. This way, no stored solar electricity is lost. Instead, the batteries are charged by the outside power source.
A UPS is a stand-alone appliance that contains the inverter, battery, and battery charger. However, some UPSs use external batteries, and PowerStream has manufactured inverters with battery chargers, so the distinctions are being blurred as features grow.
UPSs can also communicate with the equipment they power, informing it that it is in standby mode, issuing a shutdown notice, or talking with the human in the loop. Inverters do not often have this type of communication.
