6.2KW 10kWh Solar System: Run 2 AC Units + Full Home
6.2KW Solar Storage System with 10kWh Battery: The Only Kit in This Range That Powers Two Air Conditioners
Six 550W panels delivering 3,300W of solar generation. A 10kWh LiFePO4 battery doubling overnight autonomy. One all-in-one machine that keeps two AC units, a refrigerator, washing machine, two televisions, and ten or more bulbs running simultaneously — on solar, off-grid, every day.
There is a clear ceiling to what a 5kWh battery can sustain overnight in a climate where two air conditioners run after dark. This system was built specifically to break through it. At 10kWh of LFP storage and 3,300W of solar generation, it is the highest-capacity configuration in this product range — and the only one engineered to run two simultaneous air conditioning units without load-shedding any other appliance in the home.
At first glance, this system shares its inverter rating with the earlier 6.2KW all-in-one: the same 6.2KW hybrid inverter architecture, the same plug-and-play form factor, the same five appliance categories. But the differences underneath are significant. Six 550W solar panels instead of three — delivering 3,300W of base generation that can be expanded further. A 10kWh LiFePO4 battery instead of 5kWh — doubling the overnight autonomy window and enabling sustained dual-AC operation after sunset. And critically, two air conditioners running simultaneously instead of one.
This is the system for a household that refuses any compromise. Two occupied bedrooms that both need climate control. A living room and a master suite. A home office and a kitchen. Whatever the configuration, the 10kWh battery and 3,300W generation profile are sized to sustain it through the day and into the night.
Why 10kWh Changes the Overnight Equation
A single air conditioner running at 1,000W for eight hours overnight consumes approximately 8kWh. Two air conditioners running simultaneously would require 16kWh — clearly beyond what a 5kWh battery can sustain. The 10kWh LFP battery in this system, combined with the 3,300W daytime solar generation fully recharging it each day, shifts the overnight autonomy calculus entirely. With measured usage and moderate AC cycling, the 10kWh pack sustains two climate-controlled rooms through a full overnight period before solar generation resumes at dawn. This is not a theoretical ceiling — it is the engineering rationale behind specifying 10kWh for a dual-AC household profile.

Ground mounting brackets, MC4 solar cable, DC and AC wiring harnesses, pre-configured BMS, and remote engineer consultation. Everything required for installation arrives in a single consolidated shipment.
"When a customer specifies two air conditioners, I immediately calculate overnight energy demand before specifying battery size. Two 1-tonne AC units cycling through an 8-hour night require roughly 8–12kWh depending on duty cycle and ambient temperature. A 5kWh battery cannot sustain this. A 10kWh battery, recharged daily by a 3,300W solar array, is the correct engineering answer — and this system is built around exactly that calculation." — Senior Energy Systems Design Engineer, YUEGU Technical Division
Two Air Conditioners Running Simultaneously: What That Actually Requires
Running two air conditioners off solar is not simply a matter of doubling the capacity of a single-AC system. There are two independent challenges: inverter peak output to handle concurrent startup surges, and battery depth to sustain both units through an overnight period. This system addresses both:
- Each AC unit has a 1,500–2,000W startup surge
- Two units starting near-simultaneously require 3,000–4,000W peak
- The 6.2KW inverter provides headroom above this threshold
- Other loads (fridge, TV, lights) continue uninterrupted
- Two 1-tonne AC units = ~2,000W combined steady-state draw
- 8 hours overnight = ~8–10kWh consumption for AC alone
- 10kWh LFP battery sustains this with margin for other loads
- 3,300W solar array fully recharges the pack each day

Where This System Sits in the Full Range
The table below maps every system in this range to its key specifications and confirmed simultaneous load profile. The 10kWh tier represents the top of the range — the only configuration that clears the dual-AC threshold:
A Day in the Life: How the System Operates
At sunrise, six 550W solar panels begin feeding up to 3,300W of DC power into the all-in-one unit. The 6.2KW hybrid inverter converts this to AC, powering the household's morning loads immediately: refrigerator cycling, lights, televisions. As ambient temperature rises and the first air conditioner activates — drawing up to 1,000W steady-state with a 2,000W startup surge — the inverter absorbs the surge from its 6.2KW output headroom without interrupting other loads. When the second air conditioner activates, the same process repeats. Surplus solar generation throughout the day charges the 10kWh LiFePO4 battery.
After sunset, the 10kWh battery pack discharges through the inverter. Both air conditioners continue operating through the evening. The refrigerator cycles as normal. Televisions and lighting draw continuously. With disciplined load management — AC units on thermostat cycling rather than continuous full-power — the 10kWh pack sustains this load profile through an 8–10 hour overnight period before solar generation resumes at dawn. Engineer consultation, included with the system, will tailor the specific charge and discharge scheduling for your climate zone and occupancy pattern.
The lifepo4 battery chemistry underpinning this cycle maintains above 80% of rated capacity for 3,000–6,000 full cycles — more than a decade of daily full-discharge use under normal operating conditions. In practice, the 10kWh battery in a dual-AC home rarely reaches full depth-of-discharge, extending effective calendar life even further.
Expert FAQ: 10kWh Dual-AC System Buyer Questions
Can this system genuinely run two air conditioners overnight?
Yes, with appropriate AC unit sizing and thermostat management. Two 1-tonne (9,000 BTU) air conditioners in thermostat cycling mode — rather than full continuous operation — consume approximately 8–10kWh over an 8-hour overnight period. The 10kWh LFP battery, fully recharged by the 3,300W solar array each day, sustains this with a reasonable margin. The engineer consultation included with your purchase will calculate the specific overnight autonomy for your AC unit sizes, climate zone, and usage schedule.
Why does this system need 3,300W of solar when the 5kWh tier only uses 1,650W?
Battery capacity and solar generation must be matched. A 10kWh battery discharged to 80% depth each night needs approximately 8kWh of daily solar input to fully recharge. At a typical 4.5 peak-sun-hours per day, 3,300W of installed panels generates roughly 14–15kWh daily, providing both immediate household power and sufficient surplus to fully recharge the 10kWh pack. A 1,650W array generating 7–8kWh daily would struggle to recharge a 10kWh battery, leaving it progressively depleted across consecutive days. The 3,300W array is correctly sized for this battery capacity.
Is this the same inverter as the earlier 6.2KW system — just with more battery?
The inverter architecture is the same 6.2KW hybrid unit. What has changed in this configuration is the battery pack (5kWh → 10kWh), the solar array (3 panels → 6 panels, 1,650W → 3,300W), and consequently the confirmed simultaneous load profile (single AC → dual AC). The increased battery and generation capacity is what unlocks the dual-AC capability — the inverter provides the peak output headroom that was already present in the single-AC 6.2KW system.
What AC unit size is recommended for dual operation on this system?
Two 1-tonne (9,000 BTU) units are the recommended base configuration for dual overnight operation on a 10kWh battery. Two 1.5-tonne (12,000 BTU) units are also supportable for daytime operation where solar is actively generating; extended overnight dual-operation with two 1.5-tonne units draws closer to the battery's full capacity, which the engineer consultation team will model specifically for your usage profile. Units above 1.5 tonnes per zone are best discussed directly with the engineering team before specification.
