Designed for both AC and DC solar electric systems, it provides protection to service panels, load centers, or where the surge protector is directly connected. Designed for both indoor and outdoor use, the SPD is offered in three different voltages—115, 300 and 600 volts. Protection is achieved by reducing the clamping voltage to a safe level that your system can sustain and that won't damage electronic components. This Midnite Solar surge suppressor is a welcome replacement to arrestors that have been used in the past. Providing eight times the protection as previous arrestors, it is much better at clamping surges to a safe voltage.","brand":"Store Home","offers":[{"title":"Default Title","offer_id":41923065839769,"sku":"41923065839769","price":119.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0607\/9699\/3689\/files\/9a083d49-47bb-45ee-99b4-fec74824dfba.png?v=1780084226"},{"product_id":"gvboost","title":"Genasun Waterproof 105-350W 56.8V Lithium  Battery Solar Charge Controller","description":"\u003cp\u003eMarine Grade. This is a very unusual charge controller in that it can charge a battery of a HIGHER voltage than the solar panel output that feeds it. In this way, you can charge a nominal 48v lithium battery pack to a precise 56.8v using a solar panel that puts out 33v at its maximum power point. This is the only device we've found that will do that. We had these specially made by Genasun in their waterproof casing - fully potted and in a plastic enclosure. This will last forever in marine\/boat applications as well as golf cart canopies or other outdoor in the weather applications. This one is designed to charge 16 LiFePo4 cells to 56.8v using a Constant Current\/Constant Voltage charge curve perfect for our LiFePo4 cells. But it can do it from ANY of our flexible solar panels - a single panel. Why? Put a single panel on the roof of your golf cart or the deck of your john boat and use this to charge a 48v battery pack at up to 8 amps. It could not be simpler.

Battery powered off-grid systems are quite popular and 48Vdc is the current voltage of preference. Unfortunately, most 48Vdc inverters are simply a poor match for Tesla Battery Modules. Why?\u003c\/p\u003e\n\u003cp\u003eThe main problem is the Low Voltage Cutoff - the point of battery discharge where the inverter will shut down to protect the battery. Almost all 48Vdc inverters have LVCO in the 42-44V range with a very very few able to handle batteries down to 40V.\u003c\/p\u003e\n\u003cp\u003eTwo Tesla Battery Modules in series are pretty much discharged at 38V, but they are only 50% discharged at 43.2V. And so with almost all inverters on the market you are leaving 30-50% of your battery capacity on the table. That means you have to purchase TWICE the battery capacity that you would need if the inverter simply operated down to the 38V cutoff. \u003c\/p\u003e\n\u003cp\u003e\u003cmeta charset=\"utf-8\"\u003e\u003cspan\u003eThe other issue is that many of these inverters will also charge your batteries from AC - the charger is built in.  That's great, but they are traditionally designed for lead acid batteries.  They may support a bewildering array of Pb chemistry types, but ALL of the charge curves they provide are deadly to Tesla Battery Modules.  We advocate charging with a simple bulk current to 50.5volts and NO MORE.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eAnd of course most 48Vdc inverters provide 4KW to 8KW of power max.  We have located an excellent quality 15 kilowatt inverter made in China that can do 45KW for 20 seconds. It charges at 110 Amperes from 240Vac. And we have commissioned them to provide a Low Voltage Cutoff of 38Vdc and a charge limit of 50.5Vdc - ideally tuned for the Tesla Battery Modules. \u003c\/p\u003e\n\u003cp\u003eThis inverter has two modes of operation that offer some very interesting flexibility.\u003cbr\u003e\u003cbr\u003eAC PRIORITY MODE.  This allows you to pass a grid voltage THROUGH the inverter to your loads and operates primarily on grid power.  It will automatically charge your battery and cycle it every 15 days.  But on loss of grid AC input, it will transfer to battery operation within a few milliseconds.  It is an ideal \"battery backup\" system.\u003cbr\u003e\u003cbr\u003eIn BATTERY PRIORITY MODE, it does NOT pass through AC but rather generates all output power - up to 50 amps at 240vac continuously, from the battery.  In the event the battery falls below the low voltage cutoff level, it will switch to the AC input and indeed recharge the battery at the same time.  When the voltage reaches the resume level, in this case 47 volts, it will switch back to battery operation.\u003cbr\u003e\u003cbr\u003eFinally, it features a generator start output to start a generator if the source is a generator rather than the grid.\u003cbr\u003e\u003cbr\u003eBUT WAIT THERE'S MORE.  We have found that this inverter can actually replace the grid waveform to operate grid-tied inverters such as the Solar Edge and the Enphase microinverters.  This is what is used in 97% of the solar installations in the United States.\u003cbr\u003e\u003cbr\u003eNot only that, but any power produced by the solar inverters BEYOND your load needs, instead of going out to the grid goes into the batteries to RECHARGE them.  The problem is having TOO MUCH SOLAR ENERGY (the kind of problem to have) and your batteries reaching fully charged.  \u003cbr\u003e\u003cbr\u003eWith this 15kW inverter, when used in conjunction with our new ESP32 Battery Module Controller, we can signal the inverter to shift the frequency of the output to 62.5 Hz momentarily.  This causes the grid-tie inverters to shut down completely for five minutes.\u003cbr\u003e\u003cbr\u003eIn this way, we can control the grid tied inverters to prevent overcharging the batteries.\u003cbr\u003e\u003cbr\u003eFinally, this inverter features an optional remote control panel.  We INCLUDE that with every inverter instead of making it an option.\u003c\/p\u003e\n\u003cp\u003eInverter Output Specifications:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eContinuous Output Power: 15,000 Watts \u003c\/li\u003e\n\u003cli\u003eSurge Rating: 45000 Watts (20 Seconds) \u003c\/li\u003e\n\u003cli\u003eOutput Waveform: Pure Sine\/Same as input (Bypass Mode) \u003c\/li\u003e\n\u003cli\u003e100-110-120Vac \/ 220-230-240Vac\u003c\/li\u003e\n\u003cli\u003eNominal Efficiency: \u0026gt;88% (Peak) \u003c\/li\u003e\n\u003cli\u003eLine Mode Efficiency: \u0026gt;95% \u003c\/li\u003e\n\u003cli\u003eOutput Frequency:  60Hz +\/- 0.3Hz \/ 62.5Hz \u003c\/li\u003e\n\u003cli\u003eTypical Transfer Time: 10ms (Max) \u003c\/li\u003e\n\u003cli\u003eTHD: \u0026lt;
