If a battery starts at 95% and stops at 15%, the available SOC window is 80 percentage points.<\/p>\n<p>This is an approximate planning method. It is not a substitute for a manufacturer\u2019s tested usable-energy specification.<\/p>\n<h3>How Long Will a 10kWh Battery Power a House?<\/h3>\n<p><strong>Under the assumptions below, a 10kWh battery could supply a 500W average load for approximately 14.4 hours. At 1.5kW, the estimate falls to 4.8 hours.<\/strong><\/p>\n<div>\n<div>\n<div>\n<table>\n<thead>\n<tr>\n<th>Example nominal capacity<\/th>\n<th>300W average load<\/th>\n<th>500W average load<\/th>\n<th>1,500W average load<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>5.12kWh<\/td>\n<td>12.3 hours<\/td>\n<td>7.4 hours<\/td>\n<td>2.5 hours<\/td>\n<\/tr>\n<tr>\n<td>10kWh<\/td>\n<td>24.0 hours<\/td>\n<td>14.4 hours<\/td>\n<td>4.8 hours<\/td>\n<\/tr>\n<tr>\n<td>16kWh<\/td>\n<td>38.4 hours<\/td>\n<td>23.0 hours<\/td>\n<td>7.7 hours<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<\/div>\n<\/div>\n<p><em>Calculation assumptions: 80% of nominal energy is available, conversion efficiency is 90%, the average load remains constant, and no recharging occurs.

For example, a 5.12kWh battery starting at 80% and stopping at 15% has a 65-percentage-point window.

A 5.12kWh module with an assumed 80% available window and 90% conversion efficiency provides:<\/p>\n<p><strong>5.12 \u00d7 0.80 \u00d7 0.90 = approximately 3.69kWh<\/strong><\/p>\n<p>One module would fall short of that particular energy target. Two approved modules could exceed it, but the inverter, wiring, protection and battery communication must support the arrangement.<\/p>\n<p>Do not assume modules can be mixed or connected in any configuration. Confirm the permitted models and installation method before expanding.<\/p>\n<h2>4. Check Output Power and Appliance Starting Demand<\/h2>\n<p><strong>Capacity determines potential runtime. Output power determines which appliances can operate together.<\/strong><\/p>\n<p>Check the battery\u2019s continuous discharge limit and the inverter\u2019s continuous output in backup mode. Also verify starting-load capability and its supported duration.<\/p>\n<p>As an example of why detailed specifications matter, <a href=\"https:\/\/www.victronenergy.com\/media\/pg\/MultiPlus-II_230V\/en\/technical-specifications-mp-ii-230v.html\" target=\"_blank\" rel=\"noopener\">Victron\u2019s MultiPlus-II technical documentation<\/a> distinguishes continuous output at different temperatures, peak output and zero-load consumption. Those are separate figures, not interchangeable ratings.<\/p>\n<p>This is a technical example\u2014not confirmation that a particular Victron model is compatible with a Fench battery.<\/p>\n<h3>Can a Home Battery Run an Air Conditioner?<\/h3>\n<p><strong>Yes, when the battery and inverter support its running and starting requirements, but runtime depends on the actual electrical consumption.<\/strong><\/p>\n<p>Check:<\/p>\n<ul>\n<li>Electrical input power, rather than cooling capacity.<\/li>\n<li>Compressor starting demand.<\/li>\n<li>Inverter continuous and surge output.<\/li>\n<li>Other appliances operating simultaneously.<\/li>\n<li>Measured average consumption under expected conditions.<\/li>\n<\/ul>\n<p>If an air conditioner and other backed-up loads consume an assumed average of 1.5kW together, the preceding table estimates approximately 4.8 hours from a 10kWh battery.<\/p>\n<p>That estimate does not guarantee the system can start the compressor. Energy capacity and starting capability must both be adequate.<\/p>\n<h2>5.

Plan How the System Will Recharge<\/h2>\n<p>A grid-charged battery has a finite amount of energy during an outage unless another supported source can recharge it.<\/p>\n<p>Solar panels can extend backup operation only when the system supports solar generation and battery charging while disconnected from the grid. The <a href=\"https:\/\/www.energy.gov.au\/solar\/get-know-solar-technology\/batteries\" target=\"_blank\" rel=\"noopener\">Australian Government\u2019s battery guidance<\/a> describes arrangements where solar shuts down and islandable systems where it can continue supplying energy.<\/p>\n<p>Ask your installer:<\/p>\n<ul>\n<li>Will solar recharge the battery during an outage?<\/li>\n<li>What happens when the battery reaches its discharge limit?<\/li>\n<li>How does the system restart?<\/li>\n<li>What charging energy is realistic during poor weather?<\/li>\n<\/ul>\n<p>For extended outages, compare expected daily charging with daily consumption.

A compatible inverter\/charger can charge the battery from the grid beforehand. The installation still needs the equipment and configuration required for backup.<\/p>\n<p>Without another supported charging source, outage runtime is limited by the stored energy.

Determine appliance energy and peak demand first, then compare them with the module\u2019s available energy and system output. Module count must also follow the manufacturer\u2019s approved configuration.<\/p>\n<h3>How Long Will a 10kWh Battery Power a House?<\/h3>\n<p>With an assumed 80% available-energy window and 90% conversion efficiency, the estimate is 14.4 hours at a constant 500W load or 4.8 hours at 1.5kW.
