![]() electrical production.Īn off-grid inverter also integrates multiple safety features that prevent overload, overheating, over-discharging of the batteries, and many more.Ĭan Off-Grid Inverters Work Without A Battery?Ĭontrary to popular belief, off-grid inverters can work without a battery (or with an empty battery). Why is this important? Energy monitoring is crucial for an off-grid system as it helps to optimize your ratio of electrical consumption vs. This data provides you with a complete overview of your system’s daily energy metrics. your battery output power and state of charge,.your solar energy production and instant power,.For this to happen, the inverter will require an AC to DC converter with an efficiency level of 85% to 90%įunction 5: Monitoring The System And Ensuring Safetyįinally, thanks to its central role, the off-grid inverter monitors your system’s components’ power and electrical energy flux. When the off-grid inverter receives external AC power, it will power your household while charging your batteries. In this instance, an off-grid inverter accepts AC electricity from an outside source this could be a gas generator or even a grid connection. However, in some situations (bad weather or during winter), backup power is necessary to ensure a continuous electricity supply to your household. Off-grid inverters are stand-alone systems they don’t need a grid connection to operate. To perform this task, it includes a DC to AC converter - in which DC electricity comes from the battery or directly from the solar panels.įor reference, the most efficient inverters are pure sine wave types, reaching 90 to 95%. Therefore, the off-grid inverter integrates a step-down DC-DC converter to fit the correct voltage of the battery.Īdditionally, a charging algorithm ensures proper battery charging within its specification range, with an efficiency reaching +97%.įunction 3: Supplying Power To AppliancesĪn off-grid inverter uses a stable AC electricity output (110V, 60hz) to power your appliances. While MPPT provides high voltage DC electricity (150V to +500V), solar batteries are usually found in 12V to 48V DC. In an off-grid system, the second step after harvesting solar energy is to store it in the battery. To give you an idea, the efficiency of an MPPT is around 95%. In short, the MPPT uses algorithms to find the sweet spot that maximizes solar energy harvesting at all times. An off-grid inverter integrates an MPPT solar charge controller to get the most of your solar panels. Usually, off-grid inverters accept high voltage DC electricity (up to 500V DC). Monitoring the system and ensuring safetyĪ solar panel array produces DC electricity.Converting AC into DC for backup power (optional).Converting DC into AC electricity for appliances.Additionally, an off-grid inverter performs 5 primary functions:
