By specifying the DOD at 95% nearly 100% of the rated energy will be useable with a small amount of reserve power. Thus for a 16.08kWh battery 95% DOD = 15.28kWh of useable energy. This is very close to the \u2018useable energy\u2019 figures for the floor-standing residential system covered in this energy storage guide, i.e. 15.27kWh.<\/p>\n

Additional useable capacity matters for extra power in the evening for households in Indonesia, the Philippines, Malaysia, Vietnam and other Southeast Asian markets. Evening use of air-conditioning, refrigeration, water pumps, lights, internet and occasional outages on the grid all require stored energy.<\/p>\n

Still, 95% DOD does not mean unlimited backup time. Your actual result also depends on load size, inverter losses, temperature, reserve settings, and battery age.<\/p>\n

\"What<\/p>\n

What Does 95% Depth of Discharge Actually Tell You?<\/b><\/strong><\/h2>\n

Depth of discharge, usually shortened to DOD, shows how much of the battery\u2019s rated capacity has been used. A higher DOD gives you more usable energy from the same cabinet.<\/p>\n

The key point is simple. A 95% DOD rating means you may discharge up to 95% of the rated energy under the recommended system settings, leaving about 5% inside the battery.<\/p>\n

How Does the Calculation Work?<\/b><\/strong><\/h3>\n

The rated energy of the Home Energy Storage System Floor-Standing ESS<\/u><\/strong><\/a>\u00a0is 16.08kWh.<\/p>\n

\"Sistem<\/p>\n

The usable capacity calculation is:<\/p>\n

16.08kWh \u00d7 95% = 15.276kWh<\/strong><\/p>\n

Rounded down, that is approximately 15.27kWh of usable DC energy<\/strong>.<\/p>\n

This close match between calculated and listed usable energy makes the specification easier for buyers to check. The product also uses a 51.2V low-voltage architecture and a 314Ah LiFePO4 battery pack.<\/p>\n\n\n\n\n\n\n\n\n

Does 95% DOD Mean 15.27kWh Reaches Your Appliances?<\/b><\/strong><\/h3>\n

Not quite. The listed figure is usable DC energy. Electricity still passes through the inverter before reaching AC appliances.<\/p>\n

For preliminary planning, a buyer may apply a 90% conversion and operating factor:<\/p>\n

15.27kWh \u00d7 90% = 13.74kWh<\/strong><\/p>\n

That does not replace an inverter datasheet or site calculation. It simply gives you a safer working figure for early load planning.<\/p>\n

How Much Daily Backup Can 15.27kWh Provide?<\/b><\/strong><\/h2>\n

Backup duration depends more on average load than on the number of appliances. A refrigerator may have a high starting current but a much lower average hourly draw. An air conditioner may vary its power as the room cools. Pumps are another common trouble spot because their starting surge can be much higher than normal running power.<\/p>\n

Before buying, you should separate essential loads from optional loads. Keeping every air conditioner and water heater active during an outage can empty a residential battery quickly.<\/p>\n

Practical Runtime Examples<\/b><\/strong><\/h3>\n

The following estimates use 13.74kWh as a conservative available AC-energy figure.<\/p>\n\n\n\n\n\n\n\n\n
Average Running Load<\/b><\/strong><\/td>\nApproximate Runtime<\/b><\/strong><\/td>\n<\/tr>\n
500W<\/td>\n27.5 Hours<\/td>\n<\/tr>\n
1kW<\/td>\n13.7 Hours<\/td>\n<\/tr>\n
1.5kW<\/td>\n9.2 Hours<\/td>\n<\/tr>\n
3kW<\/td>\n4.6 Hours<\/td>\n<\/tr>\n
5kW<\/td>\n2.7 Hours<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

A 1.5kW essential-load group could include a refrigerator, several fans, lighting, Wi-Fi equipment, television, and one efficient air conditioner operating intermittently. Actual runtime can move in either direction. Hot weather often pushes air-conditioning demand higher, and frankly, many household estimates miss that part.<\/p>\n

The floor-standing system supports up to 7.68kW charging power and 10.24kW maximum discharging power. Power and energy should not be confused. The 10.24kW figure shows how fast energy may be delivered, while 15.27kWh shows how much energy is available.<\/p>\n

Will Frequent 95% Discharge Shorten Battery Life?<\/b><\/strong><\/h2>\n

A high usable capacity is valuable, but you should also check the cycle-life test conditions. A battery specification is only meaningful when the DOD, temperature, charge rate, and end-of-life threshold are stated.<\/p>\n

The product documentation lists 6,000 cycles at 90% DOD, 25\u00b0C, a 0.5C test rate, and 60% remaining capacity at end of life. It does not state 6,000 cycles at 95% DOD. That small distinction matters during tender reviews.<\/p>\n

Why 90% and 95% DOD Should Not Be Mixed<\/b><\/strong><\/h3>\n

The product allows a maximum recommended DOD of 95%, while its published cycle test uses 90% DOD. In daily operation, you may choose different settings:<\/p>\n

95% DOD<\/strong>\u00a0when longer backup time is the main priority<\/p>\n

90% DOD<\/strong>\u00a0for a balance between usable energy and battery ageing<\/p>\n

80% to 85% DOD<\/strong>\u00a0when the system cycles every day and backup demand is modest<\/p>\n

A larger reserve<\/strong>\u00a0during storm seasons or unstable-grid periods<\/p>\n

LiFePO4 chemistry, overcurrent protection, overvoltage protection, undervoltage protection, short-circuit protection, and overtemperature protection support safer daily operation. The battery communicates through CAN and RS485, which also helps the battery management system exchange operating data with a compatible inverter.<\/p>\n

Is the Floor-Standing ESS Suitable for Southeast Asia?<\/b><\/strong><\/h2>\n

EPOTR<\/u><\/strong><\/a>\u00a0supplies low-voltage batteries, hybrid inverters, and broader energy storage products for residential and commercial applications. For Southeast Asia, product selection should start with the installation environment rather than capacity alone.<\/p>\n

The floor-standing model uses natural cooling and does not require an active cooling system. Fewer fans can mean less noise and fewer moving parts. However, natural cooling still needs clear space around the cabinet.<\/p>\n

What Does IP20 Mean for Installation?<\/b><\/strong><\/h3>\n

The battery has an IP20 protection rating. It is an indoor product, not a weatherproof outdoor cabinet.<\/p>\n

It should be installed in a clean, dry, ventilated area such as:<\/p>\n
