Start with the energy the site uses during the hours the battery must cover, add days of autonomy if the system must ride through poor weather, then allow for depth of discharge and inverter losses. Check power separately: the battery must also deliver the inverter&#8217;s peak, such as a pump or compressor starting.<\/p><\/div><div class=\"hb-calc\"><div class=\"hd\">Worked example: home backup with solar (illustrative numbers)<\/div><ol><li>Energy used overnight and through an outage: <code>12 kWh\/day<\/code>, one day of autonomy<\/li><li>Depth of discharge 90% and inverter efficiency 95% \u2192 <code>12 \u00f7 (0.9 \u00d7 0.95) \u2248 14 kWh<\/code><\/li><li>Peak load from the inverter, e.g. <code>6 kW<\/code> \u2192 <code>6,000 \u00f7 51.2 V \u2248 117 A<\/code> from the battery<\/li><\/ol><div class=\"res\">Result: one <b>51.2V 314Ah (16.07 kWh)<\/b> unit, or a stack of rack modules, with a BMS rated above <b>~120A<\/b> continuous.

For closed-loop communication the BMS protocol must match the inverter; send the model and we confirm before quoting.<\/div><\/details><details><summary>How many cycles will a LiFePO4 storage battery last?<\/summary><div class=\"a\">Our rack and 16kWh modules are rated for over 6,000 cycles at 80% depth of discharge. Real life depends on temperature, charge rate and depth of discharge.<\/div><\/details><details><summary>Can I add modules later?<\/summary><div class=\"a\">Yes, if the new modules are the same design and the BMS firmware matches. Mixing old and new modules is possible, but the bank&#8217;s state of charge should be equalised before connecting them.<\/div><\/details><details><summary>Can the battery be installed outdoors?<\/summary><div class=\"a\">Only with an enclosure rated for it and a temperature range that suits the site. LiFePO4 must not be charged below freezing without heating.<\/div><\/details><details><summary>Do you make portable power stations under our brand?<\/summary><div class=\"a\">Yes. Battery, inverter, MPPT controller and enclosure can be configured and branded; send the power rating and capacity you need.<\/div><\/details><\/div><\/div><\/section><section class=\"hb-sec tint\"><div class=\"hb-wrap\"><h2 class=\"hb-sec-h\">Further reading<\/h2><div class=\"hb-reading\"><a href=\"https:\/\/holobattery.com\/battery-energy-storage\/\"><b>Battery Energy Storage 101<\/b><span>How storage systems are built and used.<\/span><\/a><a href=\"https:\/\/holobattery.com\/distributed-vs-centralized\/\"><b>Distributed vs Centralised Storage<\/b><span>Choosing the system architecture.<\/span><\/a><a href=\"https:\/\/holobattery.com\/the-major-components-of-an-off-grid-solar-system\/\"><b>Components of an Off-Grid Solar System<\/b><span>Where the battery fits in the system.<\/span><\/a><a href=\"https:\/\/holobattery.com\/everything-you-need-to-know-about-ups-battery\/\"><b>UPS Batteries<\/b><span>Backup power requirements and sizing.<\/span><\/a><\/div><\/div><\/section><section class=\"hb-quote\"><div class=\"hb-wrap\"><h2 class=\"hb-sec-h\">Send your storage requirements<\/h2><p class=\"hb-sub\">An engineer replies with questions or a proposed configuration.
