YACHU 10kWh Lithium Battery, 48V 200Ah

A 6.2kW inverter like the YACHU 6.2kW is a 48V unit, so it needs a 48V battery bank: one 48V (51.2V) lithium battery, such as our YACHU 5kWh (KSh 95,000) or 10kWh (KSh 160,000), or four 12V batteries wired in series. Many 5kVA hybrid inverters also run at 48V; check the label.

Four 12V 200Ah gel batteries in series store about 9.6kWh, but only about half is usable if you want them to last, so they give roughly the same usable energy as the 5kWh lithium battery. More storage means longer backup, not more power at once.

At Technics Electricals & Solar in Kiserian, YACHU lithium batteries cost KSh 40,000 for 2.5kWh (12.8V 200Ah or 25.6V 100Ah), KSh 95,000 for 5kWh (51.2V 100Ah) and KSh 160,000 for 10kWh (48V 200Ah). All use Grade A CATL cells, rated for 6,000+ cycles with a 6-year warranty, as listed.

Pick the voltage that matches your inverter: 12.8V for 12V, 25.6V for 24V, and 48V or 51.2V for 48V inverters. The warranty is the manufacturer’s; ask us for terms.

Match the battery to your inverter’s battery voltage. The YACHU 2.5kWh 12.8V 200Ah battery is for 12V inverters such as the YACHU 1.5kW hybrid; the YACHU 2.5kWh 25.6V 100Ah battery is for 24V inverters such as the YACHU 3.5kW hybrid. Both store about 2.5kWh and cost KSh 40,000 at our Kiserian shop.

Lithium costs more upfront but usually lasts much longer: YACHU lithium batteries are listed at 6,000+ cycles with Grade A CATL cells, are lighter, and let you use more of their stored energy. Gel batteries are cheaper to start, from KSh 14,000 for a 12V 100Ah. Lithium suits daily cycling; gel suits lighter or occasional backup.

• YACHU 2.5kWh lithium (12.8V 200Ah or 25.6V 100Ah): KSh 40,000, about 2.3kWh usable
• 12V 200Ah gel: KSh 30,000, about 1.2kWh usable if you use half

On our arithmetic, the lithium battery already costs less per usable kWh, before counting its longer life. These are estimates; we can compare both for your load.
