Again this is where cheaper (transformerless) inverters can often trip, especially during high summer temperatures.
If high temperatures and high loads are common, the inverter must be sized correctly to account for temperature de-rating. If multiple appliances are running at the same time, the inverter must also be able to supply continuous power under all conditions including higher temperatures. Some equipment such as water pumps, fridge compressors and air-conditioning units require very high surge (peak) power during startup, and this is where many cheaper inverters can fail. When designing an off-grid power system, the battery inverter-charger must be adequately sized and selected according to the appliances it will be running. Also, extremely high charge rates can be achieved using lithium with charging times up to 70% faster than lead-acid.Īlso, see our complete solar battery review - A detailed comparison of the latest lithium batteries from the leading manufacturers. A huge advantage of lithium is the ability to sustain a low state of charge (partial state of charge) for a prolonged amount of time without any negative effects such as sulfation which is a common problem with lead-acid batteries. Lithium batteries have a much higher energy density compared to lead-acid and are therefore lighter and more compact. This flexible sizing allows for additional capacity to be added at a later stage, which is a real bonus for both installers and customers alike. In contrast, lead-acid battery banks have a fixed size or capacity whereas lithium systems do not suffer this limitation. Over the last few years lithium-ion battery systems have become extremely popular due to their high round trip efficiency (92% to 98%), compact size, lightweight and scalability. ** Cutout voltage & SOC based on inverter settings and rate of discharge. High temperatures can drastically reduce battery life Usable capacity limited - Max 40% DoD on a regular basisĬannot sustain a partial state of charge for long periods The battery will not cutout at low SOC or low voltage** Lead-acid batteries can be discharged down to 0% state of charge if needed for backup, but it is not recommended as it can severely reduce the life of the battery.
#OFF GRID SOLAR KIT GENERATOR#
This is important, especially in emergencies or when a backup generator fails.
#OFF GRID SOLAR KIT PROFESSIONAL#
We highly recommend getting professional installation by a certified solar installer and/or master electrician and should plan on potential costs associated with this as well.One of the most significant benefits of lead-acid batteries is unlike modern lithium batteries the battery will not shut-down at a low voltage or low state of charge (SOC). You will also be responsible for optional components like current surge limiters and additional parts you may want to add. *Please note: You will need your own installation tools along with grounding rods and copper grounding wire as well as solar panel racking if necessary.
