Frequently Asked Questions
Q: What does UL1741 Listed mean for my installation?
UL1741 is the US safety standard for grid-interconnected inverters. A UL1741 Listed inverter meets the electrical safety, grid-protection and anti-islanding requirements that US utilities and local inspectors recognize — which simplifies permit approval and utility interconnection for your solar + storage project.
Q: What is split-phase output and why does it matter?
Split-phase means the inverter produces 120V on each leg (L1/N, L2/N) and 240V between legs (L1/L2) — the standard US home electrical configuration. The IP-Plus 12kW-P feeds both 120V circuits (lights, outlets) and 240V appliances (well pumps, dryers, HVAC) directly, with 12,000W continuous and 18,000VA peak power.
Q: Can the 12kW-P be paralleled for more power?
The 12kW-P is a single-unit design and does not support parallel operation. If you need more than 12kW, E-Able Power offers the IP-Plus-10kW-P, which supports 1-6 units in parallel (up to 60kW). Our engineers will help you select the right configuration for your load profile.
Q: Which battery works with this inverter?
The inverter accepts a 51.2V LiFePO4 battery bank (40-58.6Vdc range), connected externally with battery breaker protection. Charging is fully configurable: up to 160A from AC/generator and 250A from PV, with PV-priority and hybrid charging modes for lead-acid or lithium batteries.
Q: What monitoring and communication options are available?
The unit provides USB and RS485 interfaces with optional WiFi/GPRS for remote monitoring, plus dry-node control for generator or alarm signaling. The LCD panel shows system status, battery SOC and fault alarms, with power-saving mode below 25W per-phase load.
