![]() Batteries should not be overcharged and the function of the charge controller is to ensure that the battery is not over charged. Charge ControllersĪ charge controller is designed to protect the battery and ensure it has a long working life without impairing the system efficiency. A solar panel with a Voc of about 20V is required to reliably charge a 12V battery. The solar panel must be able to deliver this voltage to the battery after power losses and voltage drop in the cables and charge controller and in conditions in which the solar cells operate at a high temperature. For example a 12V battery will require 14.4V to charge it. ![]() The operating voltage of a solar panel in a stand-alone system must be high enough to charge the batteries. System voltages are typically, from 12V DC to 48V DC, larger systems will operate at 400 - 800 V DC. The solar panels need to be configured to match the system DC voltage, which is determined by the battery. Users need to know the limitations of a system and tailor energy consumption according to how sunny it is and the state of charge (SOC) of the battery. Most standalone solar systems need to be managed properly. Any AC appliances are powered via an inverter connected directly to the batteries. DC lights are normally connected to the charge controller. Any DC appliances that are connected to the battery will need to be fused. The DC electricity produced by the solar panel or module(s) is used to charge batteries via a solar charge controller. Together with power distribution panels and metering devices they complete the process. They work together with other components such as batteries, bi-directional inverters, transformers, etc. Solar modules are only one part of a standalone solar system. What are the components of a standalone solar system? Drinking water and livestock water pumping.Water quality and environmental data monitoring. ![]() Go-pure provides Standalone Solar Power Systems for: Standalone Solar Power Systems are the perfect choice for remote rural or villages to provide continuous reliable power. Power generated from a stand alone system is considered DC (direct current), and is stored in a batteries and converted to AC (alternate current). In some cases, where it is important that power is always available, some stand alone systems, known as PV-hybrid systems or island systems, may also have another source of power such as a wind turbine, bio-fuel or a diesel generator. At night, and during rainy days, all necessary power is provided by the batteries. During the day the electricity generated is used to power the home and charge the batteries. These systems typically generate from 100 Watts (very small systems) to 5 kilowatts (larger systems, multi family homes) up to 1 MW (using in the industry). Standalone solar systems (also known as autonomous, or off grid systems) are used to collect and store solar energy to be used by household appliances. They are most often used in remote areas where electricity is not available or where the connection fees of the grid are higher than the cost of an alternative energy system. Standalone Solar Power Systems are completely independent from any electric utility grid. Off-grid Standalone solar power system Off grid solar and remote power generation Monocrystalline modules, 250 Wp, 400 pcs.ĭC cables, AC cables, Multicluster box, other material Price calculation of 100 kWp off-grid PV plant ![]() The island inverters create their own grid and supply consumers. The system is designed to be installed in a place with no grid connection. The system consists of PV modules, ground-mounting systems, DC cables, inverters, AC cables, DC/AC boxes, island inverters and multi-cluster boxes.
