These choices, along with your specific household energy usage, have a large influence on the cost and benefit of a new battery storage system. In this blog, we will show you examples from SunnyDesignWeb.com that illustrate the effect of different battery and inverter combinations for a typical household.<\/span><\/span><\/strong><\/p>\n<h2><span lang=\"EN-US\" style=\"margin: 0px; font-family: 'SMA Futura Global',sans-serif;\"><span style=\"color: #000000;\">Comparing different battery system and Inverters<\/span><\/span><\/h2>\n<p><span lang=\"EN-US\" style=\"margin: 0px; font-family: 'SMA Futura Global',sans-serif;\"><span style=\"color: #000000;\">Here we will demonstrate some of the effects of changing the battery system capacity and battery inverter model.

For this household:<\/span><\/span><\/p>\n<ul>\n<li><span lang=\"EN-US\" style=\"margin: 0px; font-family: 'SMA Futura Global',sans-serif;\"><span style=\"color: #000000;\">The rating of the battery inverter did not have a large impact on energy savings. For e.g. when using a 6.4 kWh battery, the energy savings or self-sufficiency are the same whether you use the Sunny Boy Storage 2.5 or 5.0 inverter. Using a smaller battery inverter could save a significant amount of money if you don\u2019t need the Secure Power Supply feature.<\/span><\/span><\/li>\n<li><span lang=\"EN-US\" style=\"margin: 0px; font-family: 'SMA Futura Global',sans-serif;\"><span style=\"color: #000000;\">Increasing the battery capacity reduces the amount of purchased electricity from the grid (increased self-sufficiency). Remember with the Sunny Boy Storage 5.0, there are 3 battery inputs, so you can start with 1 battery and expand the system at any time.<\/span><\/span><\/li>\n<\/ul>\n<table>\n<tbody>\n<tr>\n<td width=\"112\"><strong><span lang=\"EN-US\" style=\"margin: 0px;
