At a Glance
This comparison targets buyers shopping for a portable LFP power station in the 1 kWh class for camping, home backup, or solar charging. The SOLIX C1000 and DELTA 3 Plus share the same 1800W running output and similar battery capacities (1056 Wh vs. 1024 Wh), but they diverge in ways that matter on the job.
The DELTA 3 Plus delivers a much higher 3600W surge rating, nearly 50% above the C1000's 2400W, which helps it start stubborn inductive loads like pumps and compressors. It also accepts up to 1000W of solar input versus 600W for the C1000, giving it a faster off-grid refuel path.
In device compatibility testing across 53 appliances, the DELTA 3 Plus powered 42 while the C1000 handled 38. The tradeoff: the C1000 includes a 20 ms UPS transfer, a feature the DELTA 3 Plus lacks, making it the stronger pick for always-on electronics.
