Technical explanations of battery chemistry, voltage, communication, system integration and applicable standards.
You look at the battery and see one number for voltage and another for state of charge. Your inverter may show a third number. When those readings do not match, you may assume that the battery or display is faulty. That conclusion is often too early. Voltage is a live electrical reading. State of charge, […]
Read articleA useful solar inverter maintenance routine helps you notice small changes before they become expensive problems. It also gives you a clear record, so your installer or support team can see what changed, when it changed and what has already been checked. Good maintenance does not mean you should open the inverter or try random […]
Read articleThe best off-grid solar battery is not automatically the one with the largest capacity. You need a battery that can run your essential loads, start your highest-power equipment and recharge before the next period of heavy use. The steps below show how each part of your system changes the battery you should choose. What Makes […]
Read articleAn off-grid inverter and a hybrid inverter can both work with solar panels and batteries, but they solve different problems. An off-grid inverter is designed to run a local power system without relying on the utility grid. A hybrid inverter is designed to coordinate solar, a battery and the grid, with backup functions that depend […]
Read articleIf you are comparing LiFePO4 batteries, you will probably see a percentage called depth of discharge, or DoD. It tells you how much of the battery’s stored energy has been used. Here is the simple version: if a fully charged battery has used 80% of its energy, its depth of discharge is about 80%, and […]
Read articleA LiFePO4 battery should be charged from the limits in its own manual, not from a voltage copied from another product. Match the charger to the battery voltage, allowed current, temperature range and BMS control method, then verify the result during a monitored charge.
Read articleYour battery still shows a normal voltage, but the backup time is shorter than it used to be. Is the battery ageing, is one cell reaching its limit early, or is the inverter simply stopping discharge too soon?
