Mean?\u003c\/h3\u003e\n\u003cp\u003eVictron's model numbers make choosing a regulator fairly straightforward.\u003c\/p\u003e\n\u003cp\u003eThe first number refers to the maximum permitted PV open-circuit voltage, while the second represents the regulator's maximum battery charging current.\u003c\/p\u003e\n\u003cp\u003eSo:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e150\/35 = 150V PV limit and 35A charge current\u003c\/li\u003e\n\u003cli\u003e150\/45 = 150V PV limit and 45A charge current\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe higher 150V PV allowance gives you considerably more flexibility when wiring panels in series and designing larger solar arrays.\u003c\/p\u003e\n\u003cp\u003eWhen calculating a series array, always account for the increase in panel Voc that occurs in cold conditions and keep the array within Victron's permitted PV voltage limits.\u003c\/p\u003e\n\u003ch3\u003eWhich One Should You Choose?\u003c\/h3\u003e\n\u003cp\u003eFor most 12V systems, the decision largely comes down to how much solar you're planning to install.\u003c\/p\u003e\n\u003cp\u003eThe 150\/35 is a great fit for arrays around the 500W range on a 12V battery bank, while the 150\/45 gives you room to move up to approximately 650W nominal PV.\u003c\/p\u003e\n\u003cp\u003eOn 24V and 48V systems, the same regulators can handle substantially larger arrays because the battery-side charging voltage is higher. \u003cspan class=\"contents\"\u003e\u003cspan class=\"\"\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eIf your planned array sits close to the limit of the smaller regulator, we'd generally lean toward allowing some headroom rather than designing the system right on its maximum.\u003c\/p\u003e\n\u003ch3\u003eGet More from Changing Solar Conditions\u003c\/h3\u003e\n\u003cp\u003eVictron's ultra-fast Maximum Power Point Tracking continually adjusts the operating point of the solar array to extract as much usable power as possible as sunlight, temperature and shading conditions change.\u003c\/p\u003e\n\u003cp\u003eSmartSolar also uses an MPPT algorithm designed to identify the optimum power point when partial shading creates multiple possible peaks, helping improve energy harvest in less-than-perfect solar conditions. \u003cspan class=\"contents\"\u003e\u003cspan

sources of shade, that's a genuinely useful feature.\u003c\/p\u003e\n\u003ch3\u003eBluetooth Monitoring with VictronConnect\u003c\/h3\u003e\n\u003cp\u003eBluetooth is built directly into both models,

allowing them to connect with compatible Victron GX equipment and monitoring systems.\u003c\/p\u003e\n\u003cp\u003eFor larger installations, this means your solar regulator can become part of the

High-Efficiency Operation\u003c\/h3\u003e\n\u003cp\u003eBoth regulators achieve up to 98% peak conversion efficiency and use natural cooling rather than an internal fan.
